So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...

Researchers aim to gauge how buildings constructed with reinforced concrete withstand an earthquake by conducting a simulation test at a two-story building built in the 1920s in El Centro, Calif.

In this video, we compare the strength of Sika fence post foam against rapid-setting concrete by installing two timber posts one with fence post foam and the other with concrete. We assess the ...
