Clay bricks are the most important engineering materials that can influence the quality of the construction. The quality control of the clay bricks is of prime importance to improve the quality of engineering construction. The qualities of bricks for construction applications should be checked for various types of inspection services. In this article, our inspection service was focused on compression strength test on bricks to determine their mechanical resistance and suitability for construction work. The accurate method for clay brick's production measurements has been elaborated using uniaxial compressive strength testing machine. The method was tested for a rectangular clay brick manufactured with size approximately 250 mm × 250 mm × 200 mm. The measurement method and standard uncertainty estimation of uniaxial compressive strength are briefly described in this article.

Performance of masonry is normally attributed to compressive strength of individual units, water absorption of individual units, strength of masonry mortar and the bond between mortar and individual units. Many researches in the past have contributed towards the bond strength and relevance of compressive strength of mortar in achieving good bonds. However, the quality of bricks available in India significantly vary from region the region. Thus, a need is felt in understanding bond strength of masonry. In this paper three types of mortars(total nine combinations), two types of bricks (red clay brick and fly ash brick) are considered, tests such as compressive strength, water absorption of the bricks, compressive strength of various mortar combinations, flexure bond strength and shear bond strength are presented. Failure patterns of the masonry units are also discussed. Results of the two tests show noticeable variation in bond strengths, however the shear bond strength has significant relationship with the compressive strength of mortar. The research outcome also points towards using bricks in saturated condition for achieving adequate performance.

Modern age manufacture technology requires controlled conditions for the burning and pressing of the clay bricks, while in the past these aspects weren't strictly controlled. It is expected to have different behaviours of the brick units for existing masonry buildings, as a result of the diverse fabrication technologies at different moments in time. The present paper presents a case study about the experimental testing on two batches of clay fired bricks. First batch is obtained from an existing structures and the second batch is represented by new bricks. Compression tests were conducted on specimens extracted from every batch of bricks. The experimental tests were carried out according to the current national standard for masonry units. For every tested batch of bricks, the standardized compression strength was computed as an arithmetic mean of the corrected ultimate stress. Following the large dispersion of the results for the specimens obtained from old bricks, the authors consider the standard method to determine the compressive strength of the bricks isn’t suitable for the determination of the brick batch class. Therefore, a series of probabilistic calculation were conducted by the assimilation of the experimental tests results to the processing methods characteristic for masonry. Using these procedures, the characteristic and the 5% fractile value of the compressive strength were determined for every batch of masonry units.

The objective of this study is to investigate the compressive strength and microstructural evolution of recycled aggregate concrete (RAC) containing coarse and fine clay brick aggregates. The compressive strength tests, scanning electron microscopy (SEM) observations, and X-ray diffraction (XRD) tests were performed on RAC and natural aggregate concrete (NAC) containing different coarse and fine crushed clay brick contents. The results showed that the compressive strength of NAC and RAC decreased with the increase of crushed clay brick content, and the growth rate of their compressive strength slowed down with the increase of age. At the same age and replacement rate, fine crushed clay bricks had less effect on the compressive strength of RAC than coarsely crushed clay bricks. The compressive strength of RAC aged 60 days, mixed with 60% fine brick slag and mixed with 60% coarse brick slag, is 10.49% and 14.75% lower than that of RAC aged 60 days and mixed with 0% fine brick slag, respectively. Compared with RAC, the compressive strength of NAC was more significantly affected by grading. The interfacial transition zones inside RAC had loose crystals and high porosity, with a weak adhesion between the crushed clay bricks and mortar interfaces. The crushed clay bricks did not affect the types of concrete hydration products, and Calcium-Silicate-Hydrate (C-S-H) and Ca(OH)2 crystals remained the early hydration products in RAC with crushed clay bricks. Nevertheless, the crushed clay bricks inhibited the hydration reaction of the concrete, resulting in decreasing hydration products in NAC, RAC, and RAC with crushed clay bricks.

The compressive strength of lightweight bricks produced by CV. Sinar Jaya Maros has a very high variation because there is no standard raw material composition that meets SNI standards, according to SNI 03-0349-1989 that the requirements for hollow concrete bricks for K-350 concrete quality must have a compressive strength of 350 kg/cm2. This research was conducted to design an improvement or quality improvement of hollow concrete brick products in CV. Sinar Jaya Maros. The quality improvement is in increasing the compressive strength of the concrete brick with an optimal composition. Quality improvement was carried out by using the Taguchi method experimental design to obtain the optimal combination of compositions. The orthogonal array notation used is L9(34) with material control factors in the form of cement (A), water (B), and (C), and Casting plaster (D). Data processing is carried out by calculating ANOVA on the average value and S/N Ratio with the best nominal classification. The classification was chosen because the closer to the compressive strength based on the SNI of hollow concrete bricks, the higher the quality of the concrete bricks. This ANOVA calculation is carried out to know which factors have a significant effect on the compressive strength of concrete bricks. The test conducted to determine the quality of lightweight bricks is the compressive strength test of concrete which is carried out using a compression machine. Based on the results of data processing, the ratio of the optimal composition of cement:water: sand was obtained by 2:1:3,5. Confirmation experiments prove that the compressive strength of the composition is robust.

Brick is one of largest material used in construction of infrastructure all over the world. A conventional bricks such as clay brick and concrete brick are produced from clay with high temperature kiln firing and from ordinary Portland cement (OPC) concrete respectively. Both of this activities lead to CO2 emission. The burning process requires high temperature at the same time release carbon dioxide and pollute the environment. At present, carbon emissions has become a crucial issues in the society that must be solved. Several studies had demonstrated that brick can be produced from bacteria based on Microbial Induced Calcite Precipitation (MICP). The objective of this study is to develop cement free- brick from vegetables waste with added eggshell as calcium additive to induce biocementation of brick. Brick specimen was cast in the mould size 210 x 90 x 65 mm and casting for 28 days. The study showed that there was an increased in compressive strength up to 0.062 N/mm2 as the curing period increased to 28 days which showed the occurrence of biocementation activities. SEM-EDX analysis confirmed the presence of calcite precipitation. The result indicated that vege-grout can be used as binding agent for biocementation to produce bricks.

The increasing number of population each year makes the number of building needs for houses, buildings, schools, offices and other infrastructure will increase. In general, building consumption cannot be separated from the use of bricks as a form of wall construction in building construction. The size and compressive strength of bricks circulating in the market are of poor quality which comes from fabrication, local work or home industries. In the brick-making process, bricklayers only use certain types of soil to maintain the quality of brick production. As a result, the availability of soil as the main material in brick making will decrease. Another alternative to meet the shortcomings of the brick-forming material and make it stronger and more durable, can be used as a substitute for other materials such as waste paper. The use of paper waste is an effort to find new types of building materials and to reduce environmental pollution problems due to paper waste. This study aims to analyze the concentration of the addition of paper waste ash on the strength of the bricks. The benefit of this research is as an alternative study of meeting the needs of brick raw materials for environmentally friendly buildings by utilizing paper waste ash. The results showed the effect of a mixture of paper waste ash as a clay additive on the compressive strength of normal bricks (fc '2.9 MPa). The percentage value of compressive strength with a mixture of paper waste ash 3% obtained an average compressive strength of 40.10 kg / cm2, 5% mixture variation obtained an average compressive strength of 61.48 kg / cm2 and 7% mixture variation obtained an average compressive strength average 64.12 kg / cm2 against the compressive strength of normal bricks 37.28 kg / cm2. The conclusion of this research is that the variation of the mixture of paper waste ash with a variation of 7% paper waste ash mixture exceeding 60 kg / cm² (compressive strength class III) SNI 15-2094-2000a. This shows that paper waste ash can increase the compressive strength of bricks.

The recycling of construction waste and the use of a new sintering process in the field of sintered bricks can greatly solve the problems of clay resource depletion, soil structure destruction, and high CO2 emissions that always limit the development of the sintered brick field. The study was carried out using an orthogonal experiment to derive the optimal mix ratio for the preparation of sintered bricks, and subsequently, the sintered bricks were prepared using the optimal mix ratio. The experimental results show that the maximum compressive strength of construction waste sintered brick (MRB sintered brick) prepared using high-temperature sintering is 8.1 MPa, and the water absorption is 11. When the waste glass slag is mixed with 10%, it can show a better fluxing effect in the preparation of sintered bricks by mixing construction waste with waste glass slag (MGB sintered bricks), so that the MGB sintered bricks have a higher densification. The compressive strength is 32.9% higher and the water absorption is 3.5% lower than that of MRB sintered brick. MGS sintered bricks were prepared by mixing Yellow River sedimentary sand into MGB sintered bricks. The strength of MGS sintered bricks increased with the replacement rate of Yellow River sedimentary sand, and when the replacement rate of Yellow River sedimentary sand reached 16%, the strength of the MGS sintered bricks increased by 88.9%, and the water absorption rate was reduced by 4.6% compared with the MGB sintered bricks. The sintering mechanism had significant effects on the compressive strength, weathering resistance, and frost resistance of the sintered brick. The microwave sintering process has the characteristics of high efficiency, uniform heating, selective heating, and low thermal inertia, which can increase the compressive strength of MGS sintered brick by 4.6%, reduce the water absorption by 12.9%, shorten the sintering time by 43.6%, and improve the frost resistance.
