Frontiers | Shear Design of High Strength Concrete Beams

This paper presents the criteria for the shear design of high strength concrete (HSC) beams in moment resisting frames (MRFs). The formulation of an analytical model is provided for the case of beams with longitudinal reinforcement in the presence of transverse stirrups. The model is of additive type, in the meaning that the shear resistance of the beam is evaluated as the sum of several

Use Non Shrink Precision Grout (NSPG) To Create Concrete

One reason that people are tempted to use non-shrink precision grout (also called NSPG) on concrete countertops is its name. "Non-shrink" could have some big advantages. Secondly, its compressive strength is often very high. Typical compressive strength values are 8,000 psi to 14,000 psi at 28 days, with 1 day strengths in excess of 3,000 psi.

Fiber Reinforced Concrete (FRC) for High Rise Construction

This improvement in flexural strength can be varied depending on the actual fibers used. Although not new, FRC is gradually gaining popularity in the construction industry, in particular for high rise structures. This is due to its flexural strength, especially for high seismic zones, as it will provide a better solution then reinforced Concrete.

A Study on Effects of Size Coarse Aggregate in Concrete

The most important property of concrete is its compressive strength. For the purpose of this work, there are 4 types of aggregate size used for this study were classified as aggregate size 10, size 20, size 30 and mix aggregate. Concrete cube specimens of mix 1:1:2 were prepared with water-cement ratio of 0.5. The cubes were cured using methods

Compressive Strength of Concrete and Concrete Testing

Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.
