Pumpable barite concrete

Abstract

The invention relates to the technical field of building materials and discloses pumpable barite concrete which includes, by weight, 100-500 parts of cement, 100-200 parts of fly ash, 30-150 parts ofore powder, 500-3000 parts of river sand, 500-4000 parts of fine stones, 10-50 parts of an additive, 100-400 parts of water, 30-60 parts of titanium powder, 300-1500 parts of barite sand and 500-2500parts of barite. The additive includes an expanding agent and a pumping agent according to the ratio of 7:2 or 3:5. The pumpable barite concrete has high compressive strength and flexural strength.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a pumpable barite concrete. Background technique [0002] Concrete is the most widely used building material in modern times. It has the advantages of abundant raw materials, low price, simple process, high strength and good durability. [0003] However, concrete often has adverse consequences such as cracking, leakage, and loss of prestress. The reason for analysis is that the compressive strength and flexural strength of concrete are not enough, and the performance of concrete leads to structural deformation and reduced service life of the building. Contents of the invention [0004] The invention aims at the shortcomings of poor concrete compressive strength and flexural strength in the prior art, and provides a pumpable barite concrete. [0005] In order to solve the above technical problems, the present invention is solved through the following technical soluti...
