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 of mortars at both

What watercementsand ratio gives the strongest mortar?

Make sure you have Portland Cement, not mortar mix or some other pre-mixed product. Adding your ratios to a pre-mix would greatly reduce the cement content, resulting in a disaster such as you described. For a stronger mix, increase the cement a bit, and reduce the sand.

Concrete strength Understanding Cement

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful The processes of 'setting' and 'hardening' are often confused Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may
