Abstract

The invention relates to the technical field of building materials, and particularly discloses environment-friendly lightweight aggregate concrete and a preparation method thereof. The green environment-friendly light aggregate concrete disclosed by the invention is mainly prepared from the following raw materials in parts by weight: 220 to 280 parts of Portland cement, 200 to 250 parts of water, 180 to 250 parts of machine-made sand, 130 to 180 parts of river sand, 120 to 150 parts of ceramsite, 50 to 100 parts of fly ash, 5 to 10 parts of an additive and 5 to 10 parts of a binder. The preparation method of the green environment-friendly lightweight aggregate concrete comprises the following steps: (1) uniformly mixing and stirring Portland cement, machine-made sand, river sand, ceramsite and fly ash to obtain a mixture; and (2) adding the water into the mixture, conducting mixing and stirring, adding an additive and a binder, and uniformly conducting mixing and stirring to obtain the product. The green environment-friendly light aggregate concrete provided by the invention is relatively good in durability and strength.

Description

technical field [0001] The application relates to the technical field of building materials, more specifically, it relates to a green and environment-friendly lightweight aggregate concrete and a preparation method thereof. Background technique [0002] Sometimes some problems are encountered in the construction of highway projects. For example, the distance between the surrounding houses and streets is too close to the highway, which makes the construction site of the highway project very small. and supplies have brought great difficulties. In this case, it is necessary to do the road widening work on the current site without increasing the additional site area. In order not to affect the original road and surrounding buildings, deformation of the road foundation should be avoided as much as possible during road widening. [0003] Due to the great advantages of light aggregate concrete compared with ordinary concrete, it can effectively deal with the problem of road widen...
