Streszczenie:
This study develops mathematical models for obtaining optimum flexural strengths of normal laterised(NLC) and high strength laterised concretes (HSLC). The models can be expressly used to evaluate the indirect tensile strengths of both types of concretes without going through the traditional methods of mix design. Optimum mixing ratios and optimum flexural strengths predicted are also supplied by the models. The three point load method was adopted for testing for the flexural strengths. Laterite, has been widely used to partially or wholly replace sand in concrete with resultant low strengths.

Flexural and tensile strengths of concrete are of great importance in structural engineering. Understanding the flexural strength of concrete helps designers prevent and control development of cracks in concrete elements, ensuring durability. In addition to serviceability, shear, bond failure and flexural capacity in concrete members are directly linked to the tensile strength of the concrete. When compared to flexural and tensile strengths, determination of the compressive strength of concrete is easier to carry out in the field. It is therefore, customary to determine the compressive strengt

The use of fiber reinforced plastics (FRP) in repairing and strengthening bridges has been researched in recent years. In particular, attaching unidirectional FRP to the tension face of reinforced concrete beams has provided an increase in stiffness and load capacity of the structure. However, due to the brittle nature of the unidirectional FRP, the ductility of the beam decreases. One possible solution to this problem is the use of cross-ply or off-axis FRP laminates.

The stress-strain characteristics of concrete developed in flexure is very important for flexural strength design of reinforced concrete (RC) members. In current RC design codes, the stress-strain curve of concrete developed in flexure is obtained by scaling down the uni-axial stress-strain curve to account for the strain gradient effect. Therefore, the maximum concrete stress that can be developed under flexure is smaller than its uni-axial strength, and the use of which always underestimates the flexural strength of RC beams and columns even though the safety factors for materials are taken

Conventional concrete is characterized by its brittleness, displaying a flexural strength that falls within the range of 10-15% of its compressive strength. Incorporation of fibers into concrete enhances various mechanical properties, including tensile strength, flexural strength, and ductility. An advantageous feature of FRC is its capacity to consider cracked concrete below the neutral axis in the cross-section of a beam to some extent. Important factors influencing the flexural strengths of

Fiber Reinforced Polymer (FRP) has been used in construction as it is lightweight, has flexural strength, is more durable and resistant to corrosion, impact, and fire. Finite Element Analysis (FEA) is a modern technique to predict the tensile behavior and cracking pattern of structural members using nonlinear finite element analysis (NLFEA). In this current study, 11 specimens of Glass Fiber Reinforced Polymer (GFRP) reinforced concrete (RC) Beams with different reinforcement bars (#5, #6 and #8 bars) and spacing (30mm, 38mm and 50 mm) along with two different concrete strengths (Normal and hi

PC is a type of concrete which is well known for its low strength and high infiltration rate. PC is made up of cement, coarse aggregate, water and with little or no fine, that is the reason PC is also known as no fine concrete. The fine content in PC tends to improve the strength of the concrete yet it adversely affects the infiltration of the PC. Therefore, in this study the pumice stone fine was incorporated in pervious concrete to make a PC with improve strength without sacrificing its infiltration. This experimental investigation helps to explain the effect of pumice stone when used as fin

Mixture-proportioning studies and submittals are an integral part of the pavement design and planning process as outlined in the Unified Facilities Guide Specification 32 13 14.13 for Department of Defense airfield pavements. Many aspects of the required testing are time-consuming due to the duration of the test (e.g., alkali–silica reaction experiments) or to the required concrete age at testing (e.g., compressive or flexural strength testing). Time awaiting testing results often delays projects and adds cost. The objective was to develop an accelerated testing requirement for flexural streng

Two commercial superabsorbent polymer (SAP) formulations were used to internally cure cement pastes, mortars, and concretes with a range of water-to-cement ratios (w/c 0.35–0.52). The following properties were determined as a function of cement chemistry and type, use of chemical admixtures, use of slag, and batching parameters: SAP absorption capacity, fresh mixture workability and consistency, degree of hydration, volumetric stability, cracking tendency, compressive and flexural strength, and pumpability. SAP internal curing agents resulted in cementitious mixtures with improved hydration, a

The American Association of State Highway and Transportation Officials R 100 standard provides instructions for making and curing concrete test specimens in the field. However, further research is needed to compare the strength of the field-cured specimen with the strength of the actual in-place concrete item. The purpose of this combined laboratory and field study was to evaluate field-curing methods of concrete specimens for estimating the early opening strength of an in-place concrete item.

The research discussed in this progress report has been proposed to study the interface shear transfer in applications for partial-depth concrete repairs and for topping applications on precast elements. This research comprises two phases of laboratory testing. Phase 1 was developed to study the (local) interface bond strength of slab specimens through direct shear tests and direct tensile pull-off tests. Phase 2 comprises flexural tests on beam specimens to assess interface shear strength under combined bending and shear.

This project focused on evaluating the effects of fire-induced damage on concrete bridge elements, including prestressed concrete bridge girders. A series of controlled heating experiments, pool fire tests, material tests, and structural loading tests were conducted. Experimental results indicate that the portion of concrete subjected to temperatures higher than 400°C loses significant amounts of calcium hydroxide (CH). Decomposition of CH increases porosity and causes significant cracking. The portion of concrete exposed to temperatures higher than 400°C should be repaired or replaced. When s
