Compressive Strength of Concrete

2020/04/17Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc. Test for compressive strength is carried out either on a cube or cylinder.

Strength and Durability Assessment of Portland Cement

We investigated the effects of hydrogen-rich water (HRW) on the strength and durability of Portland cement mortars. We comparatively assessed the performances of HRW-based mortars (HWMs) with respect to cement mortars fabricated from control water (CWM). The results indicate that the use of HRW significantly improves the compressive, flexural, and splitting tensile strength

Compressive strength of concrete

2020/12/21Concrete gains 16 % of its initial strength within 24 hrs, whereas concrete gains 65% of the target strength by the time of 7 days of its casting and curing. Till 14 days concrete shows 90% of the target strength and there after the gain in strength slows down and it takes 28 days to achieve 99% of its strength.
