BAIJIAN - Third party testing organization
The materials actually used in the project should be used during the trial preparation. The mixing time of cement mortar and mixed mortar is not less than 120s; Mortar mixed with fly ash or additives、 with a mixing time of not less than 180 seconds. Conduct trial mixing according to the calculated mix ratio、 measure the sinking degree and layering degree of the mixture. If it cannot meet the requirements、 adjust the material dosage until it meets the requirements; The obtained result is the benchmark mix ratio When testing the strength of mortar、 at least three different mix ratios should be used、 one of which is the benchmark mix ratio、 and the cement dosage of the other two mix ratios should be increased and decreased by 10% compared to the benchmark mix ratio. Under the condition of ensuring that the sinking degree and layering degree are qualified、 the water consumption or admixture dosage can be adjusted accordingly. The three sets of mix proportions are molding、 curing、 and measuring the 28d mortar strength、 in order to determine the mix proportion that meets the trial strength requirements and has the lowest cement content as the mortar mix proportion
