Problems solved by technology

It takes a certain process and time for this reaction to change from physical adsorption to chemical reaction. With the increase of hydration age, for the coagulation without lithium slag, the hydration product layer deposited on the surface of cement particles becomes thicker. , its hydration becomes more and more difficult, and the speed of forming C-S-H gel in its hydration product becomes slower and slower

Abstract

The invention discloses high-performance lithium slag pump concrete. The proportion of mixture of the concrete is cement:water:mineral powder:fly ash:lithium slag:sand:gravel:synergist: additive being (340-520):(165-200):(0-50):(0-50):(40-150):(700-850):(1,000-1,100):(2-3.5):(7-12) according to the component unit of kg / m<3>. By means of selection of the raw materials and design of proportioning, the high-performance lithium slag concrete which is good in working performance, mechanical performance and durability and can be used for pumping is obtained.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a high-performance lithium slag pumping concrete. Background technique [0002] Usually contains SiO 2 , Al 2 o 3 All industrial waste residues are potentially active, and through appropriate technical means, the inherent deficiencies of waste residues can be made up for. At present, at home and abroad, alkali components are used to activate various slag bodies through chemical and physical methods to prepare clinker-free and clinker-less cementitious materials, eliminating the need for calcination and multiple grinding processes. At the same time, it also promotes the sustainable development of cement and concrete not only to obtain good economic and social benefits, but also to achieve good environmental benefits, and is expected to develop concrete materials into new environmental materials that are coordinated with the environment. [0003] With the developm...
