Concrete modifier

Abstract

The invention discloses a concrete modifier. The concrete modifier is prepared from the following raw materials in parts by mass: 100 to 150 parts of superfine slag powder, 30 to 50 parts of wood powder, 20 to 40 parts of sodium silicate, 20 to 40 parts of diatomite, 10 to 20 parts of hydroxyethyl cellulose, 5 to 15 parts of silicon oil and 5 to 10 parts of super absorbent polymer. The concrete modifier disclosed by the invention has the advantages of low cost and convenience in use; the concrete modifier is directly added in the process of adding water into concrete raw materials for stirring; the pore structure of concrete can be compacted, the slump and expansion of the concrete are improved, and the structural strength of the concrete is improved; and in addition, the water-retaining property of the concrete is improved and the curing period of the concrete is shortened.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete modifier. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete that uses cement as the cementitious material, sand and stone as the aggregate; it is mixed with water in a certain proportion and stirred. It is also called ordinary concrete, which is widely used in civil engineering. Concrete has been widely used in the field of civil engineering because of its excellent physical and mechanical properties, and it is currently the most widely used building material. However, the strength of the traditional concrete structure needs to be improved, it is prone to cracking, and the curing period is long. The traditional concrete needs to be exposed to water for about 10 days. Contents of the i...
