The meaning of WATER-CEMENT RATIO is the ratio of mixing water to cement in a concrete expressed by volume or by weight or as the number of gallons of water per bag of cement.
A detailed research carried out to ascertain the influence of sand ratio on waste glass powder concrete is reported in this paper. Tests were designed to facilitate comparisons between concretes with waste glass powder and concretes without waste glass powder. The replacement level of cement by waste...
levels with well-controlled loading paths, static tests have been carried out on concrete samples by mean of a very high-capacity triaxial press (stress levels on the order of 1 GPa). It is a longstanding fact that the water/cement ratio (W/C), upon entering the concrete composition, is...

the ratio of the autogenous shrinkage in total shrinkage of concrete at very early age increase evidently with water-cement ratio decreasing.During 1 day age,the autogenous shrinkage develops rapidly and at a low water-cement ratio,the total shrinkage is mostly attributed to the autogenous shrinkage...
The effect of dry density,water-cement ratio,the addition of fly ash,and sand content on the porosity and pore distribution of foamed concrete is investigated.Digital microscopy and Image J software are employed to examine the landscape ... F Geng,W Yin,J Xie,... - 《Transactions of Nanjin...
In order to study the influence of water-cement ratio on reinforced concrete beam, the cracking load and cracking time, the position of cracks, distribution and development condition, ultimate load and time of failure of the beam were defined as main observation indexes. Nine RC beams of differe...
During production, storage, and transportation of cement, an uncontrolled variation in the gypsum-hemihydrate ratio may occur, which may cause an uncontrolled effect on the workability properties of the fresh concrete. In the present paper, the results of an experimental investigation on the effect ...
