properly conduct concrete mix design, trial mixing, and repeated verification, and select the optimized mix ratio.
the mix ratio design should establish the glue ratio, sand rate, active admixtures, admixture dosage, etc. according to the requirements. the glue ratio is directly related to the strength and workability of the mixture. if the glue ratio is large, the strength is generally high and the workability is good. on the contrary, the strength…
