Abstract

The invention discloses high-strength base sealing concrete and a preparation technology thereof. The base sealing concrete is prepared from the components, in parts by weight: 100-300 parts of cement, 40-100 parts of silica sand, 10-20 parts of modified bamboo fiber, 5-15 parts of basalt fiber, 30-50 parts of carboxylic butadiene-styrene latex, 10-30 parts of alkyl sodium sulfonate, 5-15 parts ofsodium fluosilicate, 10-30 parts of zirconium oxide, 10-40 parts of water reducing agent and 50-80 parts of water. The preparation technology is simple, the prepared concrete is high in strength, high in anti-permeability performance, high in durability and excellent in anti-fatigue performance, and can ensure draught fan equipment to work stably for a long term under coupling effects of a plurality of factors such as dynamic and static loading, sea water intrusion and the like.

Description

technical field [0001] The invention relates to the technical field of back-sealing concrete preparation, in particular to a high-strength back-sealing concrete and a preparation process thereof. Background technique [0002] Concrete is the largest construction material today, and high-performance concrete represents the development direction of concrete technology. In recent years, with the vigorous development of the domestic construction industry, the requirements for the strength and durability of the concrete consumed in the construction process have been continuously increased. At present, the strength, impermeability and durability of concrete cannot meet the requirements of society, and further development and improvement are needed. Contents of the invention [0003] The object of the present invention is to provide a high-strength back-sealing concrete and its preparation process, so as to solve the problems raised in the above-mentioned background technology. ...
