31-12-2017· Ultra-high performance concrete (UHPC) has superior mechanical properties and durability to normal strength concrete. However, the high amount of cement, high environmental impact, and initial cost are regarded as disadvantages, restricting its wider application. Incorporation of supplementary cementitious materials (SCMs) in UHPC is an effective way to reduce the amount of cement needed …
Evaluation of Compressive Strength: Compressive strength is the most common test conducted on hardened concrete, partly because it is an easy test to perform, and partly because most of the desirable characteristic properties of concrete are qualitatively related to its compressive strength. To evaluate the compressive strength cubes of size 150 mm x 150 mm x 150 mm were casted using C.I. mould.

Home / pressive stregth of concrete. Creep and shrinkage of concrete, Creep and shrinkage of concrete are two physical properties of concreteThe creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers Unlike the creep of ...
17-10-2020· The strength ratio between 100 × 100 mm cores and air-cured 150 mm cubes was on average 1.01 for all concrete mixes, while the strength ratio of air-cured 150 × 300 mm cylinders and 150 mm cubes was on average 0.85, which agreed with the ratios 0.82–0.85 reported by Zabihi & Eren. 43 There were also clear differences between different concrete types in the above-mentioned ratios.
