Water cement ratio is stated as the amount of water used to the significant amount of cement in the mixture by weight for proper workability. A minimum water-cement ratio of about 0.3 by weight is necessary to ensure that the water comes in contact with all the cement particles, Which assures complete hydration of the cement paste If you are interested in our products, consult now to get a more favorable price;
