Abstract

The invention discloses a method for measuring the pressure water absorption rate of haycite and a method for reducing the pressure slump loss of a haycite concrete pump, provides a haycite pressure water absorption rate concept, realizes measurement by a method for jointly measuring a test sample by soaking the test sample in water, and further provides a method for reducing the slump loss of haycite concrete by determining a corresponding mixing water surplus according to the measured pressure water absorption rate of the haycite. According to the method, the problem of increase of the slump loss of concrete caused by a fact that the haycite adsorbs a large amount of water in concrete cement slurry easily in conveying and pumping processes can be solved.

Description

technical field

[0001] The invention belongs to the technical field of detection methods for concrete working performance and preparation control of ceramsite concrete, and relates to a method for measuring the pressure water absorption rate of ceramsite in concrete and a method for determining the appropriate mixing water abundance through the measured ceramsite pressure water absorption rate To reduce the slump loss of ceramsite concrete. Background technique

[0002] Ceramsite concrete is a kind of lightweight aggregate concrete. The internal structure of lightweight ceramsite is characterized by fine and dense honeycomb micropores that are not connected to each other. These micropores are formed due to the gas being enclosed in the shell, and include open pores and closed pores. Due to the loose and porous structure inside the ceramsite, the ceramsite concrete is pumped to the formwork pouring process, and the water in the cement slurry will gradually enter the clos...
