Inspection method for rapidly measuring water demand ratio of fly ash

Abstract

The invention relates to the technical field of fly ash water demand detection, and in particular relates to an inspection method for rapidly measuring the water demand ratio of fly ash. The inspection method comprises the following steps: adding water into a cement paste stirrer, weighing 300g of cement, adding into the cement paste stirrer, stirring, continuously adding water until the fluidity of the stirred paste reaches 200 to 210mm, and obtaining contrast paste; adding water into the cement paste stirrer, weighing 210g of cement and 90g of fly ash, adding the weighed cement and fly ash into the cement paste stirrer, stirring, and continuously adding water until the fluidity of the stirred paste reaches 200 to 210mm to obtain test paste; and the water demand ratio of the fly ash being the ratio of the water consumption of the paste reaching the specified fluidity to the water consumption of the test paste reaching the specified fluidity. Compared with the prior art, the detection method has the advantages that few steps are needed, errors are small, the water demand ratio of the fly ash can be accurately detected only by performing the test for 1 to 2 times, the detection time is shortened, and resources are saved.

Description

technical field [0001] The present application relates to the technical field of detection of fly ash water demand, in particular to a test method for quickly measuring the fly ash water demand ratio. Background technique [0002] At present, the fluidity of the test mortar and the comparison mortar is usually determined according to the detection principle of the fly ash water demand ratio in the GB / T1596-2017 national standard specification, and the amount of water added when the fluidity of the two reaches 130-140mm The ratio determines the water demand ratio of fly ash to measure the water demand of fly ash. [0003] However, in the above detection method, workers need to weigh the corresponding weights of cement, standard sand and fly ash in sequence, and then make mortar according to international standards, and then use the fluidity jump table to test the fluidity. In order to ensure the accuracy of the test, it is often necessary to test 4 to 5 times to accurately m...

[0003] However, in the above detection method, workers need to weigh the corresponding weights of cement, standard sand and fly ash in sequence, and then make mortar according to international standards, and then use the fluidity jump table to test the fluidity

In order to ensure the accuracy of the test, it is often necessary to test 4 to 5 times to accurately measure the water demand of fly ash, which takes a long time, wastes resources, and costs high, so it needs to be improved
