Abstract

The invention discloses a process for using a latter admixing method to produce green concrete. According the process, microorganism modified oil palm fruit shell ash is used for replacing parts of cement to prepare a new concrete reinforcing additive, then the latter admixing method is adopted to produce the green concrete, and the produced concrete is short in setting time, high in strength, long in service life and stable in quality and is resistant to abrasion, pressure and seepage.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a process for producing green concrete by a post-mixing method. Background technique [0002] With the continuous advancement of concrete technology, people expect concrete to have more excellent properties, such as high strength, high workability and high durability. In addition to ordinary C10, C30, and C40, the appearance of high-performance concrete such as C60, C80, etc. has aroused the interest of scholars and engineers at home and abroad, and has been used in nuclear power nuclear islands, marine structures, high-rise buildings, viaducts, and cut-off walls. Under construction. The research and application of high-strength and high-performance concrete started relatively late in China, but the research and application of high-performance concrete have developed rapidly in the past ten years, and the continuous development of new, high-efficiency, and composite ...
