Concrete compression-resistant modifier

Abstract

The invention discloses a concrete anti-cracking modifier, which is made by the following raw materials in parts by weight: 2.5-5 parts of periodate ligin, 1.2-1.8 parts of 4-isooctyl phenol, 1.5-2.8 parts of tributyl citrate, 0.8-1.5 parts of dehydroacetic acid, 2.3-2.8 parts of acacia gum, 5-10 parts of corn protein powder, 1.5-2.6 parts of tri-benzyl phenol polyoxyethylene ether and 0.5-1.1 parts of formaldehyde. Compared with the existing concrete modifier, the concrete anti-cracking modifier has features of high surface toughness, low brittleness and improved low-temperature stability of concrete. By adopting the anti-cracking modifier, the concrete has features of reduced thermal conductivity, reduced heat absorption value, increased thermal resistance and cold resistance, reduced temperature susceptibility and better high / low temperature stability of the asphalt concrete. The anti-cracking performance of roads of the concrete is improved, and furthermore the service life of the roads is prolonged and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to a concrete compression modifier, which belongs to the field of building materials. Background technique [0002] In recent years, the asphalt road business has developed rapidly, but there are generally problems in technology and quality of asphalt pavement, which are mainly reflected in the durability of road engineering and the early damage of the road surface, especially in some bad weather conditions and heavy traffic loads. Therefore, higher requirements are placed on the performance of asphalt concrete. Usually, asphalt concrete is obtained by compacting the homogeneous mixture of heated asphalt, coarse and fine aggregates and filling materials (mineral powder, cement, etc.) according to the appropriate mixing ratio. Generally, the temperature stability of asphalt concrete is the main factor affecting the durability of the road, and the water stability of asphalt concrete is the main factor affecting the early failure of...

Problems solved by technology

Generally, the temperature stability of asphalt concrete is the main factor affecting the durability of the road, and the water stability of asphalt concrete is the main factor affecting the early failure of the asphalt pavement. A large number of cracks, pits, spalling, aggregate shedding, and even structural damage, which has to be repaired or maintained, resulting in a great waste of resources and economic losses
