    From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and 28 days respectively.

    Jan 17, 2015 Concrete may be good at withstanding vertical loads but it is comparatively vulnerable to lateral loads. That is why concrete structures are often reinforced with steel, which has complementary characteristics weak on vertical loads, strong on lateral forces. If a concrete structure receives an extra lateral or horizontal load, it could buckle.
