摘要
The present invention relates to a concrete pumping method using activation of a lubricant layer. The present invention transfers concrete by injecting a lubricant layer activator which can lower pressure required for concrete transfer when applying high pressure to the concrete to be transferred for a long distance. That is, the lubricant layer is formed between the concrete and an inner circumferential surface of a pumping pipe. In the present invention, the lubricant layer activator (liquid chemical) is injected so that the lubricant layer is further activated. Therefore, the pressure required for the concrete transfer can be lowered. In the present invention, the liquid chemical is mixed with water to be used in a shape of the liquid chemical after a surfactant, a thickener and a setting accelerator are mixed.;COPYRIGHT KIPO 2020
