Problems solved by technology

[0003] At present, there is no uniform standard for the ratio of foam concrete. The versatility of the subgrade for different rock and soil conditions and environmental conditions is relatively poor. Research on the ratio of foam concrete suitable for local rock and soil conditions and environmental conditions can improve the engineering performance of foam concrete. It is of great significance to the popularization and application of foam concrete technology

Abstract

The invention discloses foam light-weight concrete and a preparation method thereof and relates to the technical field of preparation of concrete. A raw material formula comprises the following components in parts by mass: 150 to 200 parts of geopolymer cement, 1.0 to 1.5 parts of a water reducing agent, 4 to 5 parts of an early strength agent, 3 to 5 parts of an additive, 2 to 4 parts of fibers,15 to 20 parts of a foaming agent, 10 to 12 parts of a gel material, 1 to 3 parts of diatom ooze and 100 to 120 parts of water; the preparation method of the foam light-weight concrete comprises the following steps: (1) pouring the geopolymer cement, the water reducing agent, the early strength agent, the fibers, the gel material, the diatom ooze and a proper amount of the water into a stirring tank according to the ratio and stirring and mixing; (2) continually adding the foaming agent into the stirring tank and continuously stirring for 12 to 14min; then adding the additive and continuouslystirring for 35 to 40min. The concrete prepared by the method has the advantages of light weight and good commonality.

Description

technical field [0001] The invention relates to the technical field of concrete preparation, in particular to a foam lightweight concrete and a preparation method thereof. Background technique [0002] Foam lightweight concrete is a kind of lightweight filling material, which is composed of cement slurry and a certain proportion of small enough stable bubble groups, which are fully mixed and stirred to form a fluid, and finally solidified and formed. Foam lightweight concrete is light in weight, high in strength, wide in adjustable range, good self-supporting, convenient and fast in construction, and has good technical economy. The application of foam concrete materials to the back filling of road and bridge abutments is an innovative technology that changes the conventional abutment back filling process. The foam concrete material has the advantages of greater strength than conventional backfill, forming a whole after filling, good impact resistance, no lateral pressure, a...
