The use of recycled aggregates from demolished constructions as coarse aggregates for concrete becomes a need to reduce the negative effects on the environment. Internal curing is a technique that can be used to provide additional moisture in concrete for more effective hydration of cement to reduce the water evaporation from concrete, increase the water retention capacity of concrete compared to the conventionally cured concrete. High strength concrete as a special concrete type has a high strength with extra properties compared to conventional concrete. In this research, the combination of p

Even for the construction of conventional buildings, materials for construction expense is unnecessarily rising, and this is becoming a major factor impacting the global housing market. This has made research into the economy of building materials necessary. In this regard, concretes have been created that partially substitute conventional aggregates with Demolished Concrete Waste (DCW) as coarse and fine aggregates. By bridging concrete cracks, the steel fibers’ characteristic helps to increase the inherent tensile strength of the material. For the purposes of this study, three distinct combi

Regarding the basic material behavior, research of material proportions formulations, mix design formulas and inventions towards the development of a high-performance geopolymer concrete, were conducted. The latest looked into the effects of molar activator concentrations to the 28 days compression strength, and the strength development as a function of

The use of hemp fiber is capable of increasing the compressive and tensile strength, along with enhanced ductility in concrete. Shell ash also contains calcium compounds that improve the properties of concrete. Therefore, this study aimed to measure the compressive and tensile strengths of concrete as well as the chemical functional groups of hemp fiber. To achieve this, hemp fiber (additive) and 6% shell ash (filler) were added to the concrete mixture, targeting a design strength of 25MPa. The results showed that the average compressive strength of concrete after 28 days obtained a minimum va

The consumption of artificial light, especially in urban areas, leads to global warming. As a remedy this light transmitting concrete acts as a solution for global warming. Light transmitting concrete is made with cement ,water , very fine sand and thousands of optical fibres reinforced in concrete from one face to another face which guide the light passing through it. Light transmitting concrete is a concrete that is improved in terms of transparency by installing optical fibres into concrete. We used 3% of optical fibre in this concrete.

The study analyzed the influence of recycled aggregates in the mechanical properties of conventional concretes and evaluated the difference between measured and predicted values of elasticity modulus. The incorporation of WPA in concrete showed better mechanical results compared to the concretes produced with RCA. Measured elasticity moduli were lower than moduli predicted by NBR 6118:2014 and fib Model Code 2010, while measured results were grea

This approach addresses waste issues and presents a sustainable material alternative to conventional sand, investigating different SGT proportions (ranging from 0% to 100%) to replace fine aggregate in structural concrete. This study examined the fresh, mechanical, and durability properties of concrete containing SGTs.
