Stage 2: Grinding, Proportioning, and Blending The crushed raw ingredients are made ready for the cementmaking process in the kiln by combining them with additives and grinding them to ensure a fine homogenous mixture The composition of cement is proportioned here depending on the desired properties of the cementDuring the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process Gypsum is added to control the “setting of cement” If not added, the cement will set immediately after mixing of water leaving no time for concrete placing Suggest CorrectionsGypsum is added in the Final stages of preparation of cement
Water/Cement Ratio an overview | ScienceDirect Topics
The water–cement ratio is a convenient measurement whose value is well correlated with PCC strength and durability In general, lower water–cement ratios produce stronger, more durable PCC If natural pozzolans are used in the mix (such as fly ash), then the ratio becomes a watercementitious material ratio (cementitious material = portland2022年5月5日· It’s generally not a good idea to add water unless the concrete really is too dry and the mix is difficult to work In that case it might be that a properly added gallon or two of water per yard of concrete may be appropriate for a particular delivery and purpose, but it might not be Without performing an actual slump test, you’re guessingCan You Add Water to Concrete?
