Embodiment 1

[0013] A concrete curing agent with strong anti-cracking performance is prepared from the following raw materials in parts by weight: 45g of sodium silicate, 35g of calcium carbonate, 25g of aluminum silicate, and 50g of polypropylene fiber. The above raw materials are mixed, stirred evenly, crushed and ground into powder, and a stabilizer with a weight of 0.01% of sodium silicate is added, mixed evenly, and the finished product can be obtained.

Embodiment 2

[0015] A concrete curing agent with strong anti-cracking performance is prepared from the following raw materials in parts by weight: 20 g of sodium silicate, 20 g of calcium carbonate, 10 g of aluminum silicate, and 25 g of polypropylene fiber. The above raw materials are mixed, stirred evenly, pulverized and ground into powder, and a stabilizer accounting for 0.015% by weight of sodium silicate is added, mixed evenly, and the finished product can be obtained.

Embodiment 3

[0017] A concrete curing agent with strong anti-cracking performance is prepared from the following raw materials in parts by weight: 40g of sodium silicate, 30g of calcium carbonate, 20g of aluminum silicate, and 30g of polypropylene fiber. The above raw materials are mixed, stirred evenly, pulverized and ground into powder, and a stabilizer with a weight of 0.02% of sodium silicate is added, mixed evenly, and the finished product can be obtained.

Abstract

The invention discloses a high-cracking-resistance concrete curing agent. The concrete curing agent is made of, by weight, 20 parts to 45 parts of sodium silicate, 15 parts to 35 parts of heavy calcium carbonate, 10 parts to 25 parts of aluminum silicate and 25 parts to 55 parts of polypropylene fibers. By means of the concrete curing agent, the polypropylene fibers are added in the concrete curing agent, and accordingly, microcracks caused by factors of concrete solid plastic shrinkage, air shrinkage, temperature variation and the like can be controlled effectively, forming and developing of cracks can be prevented and restrained, the crack-resistant anti-penetrability performance and the shock resistance and aseismic capacity are improved greatly, cracks of concrete can be reduced effectively, and the concrete curing agent is particularly applicable to construction projects of houses, roads, bridges and the like.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a concrete curing agent with strong crack resistance. Background technique [0002] Concrete is the most widely used and used building material in the field of construction engineering in the world. It is widely used in houses, bridges, roads and other projects. Concrete cracks are a common phenomenon in engineering. Concrete cracks mainly include shrinkage cracks caused by shrinkage deformation and load (stress) cracks caused by external loads. The appearance of concrete cracks affects the use function of the project, ranging from affecting the service life of the project, causing water leakage in the building, and causing collapse of houses, bridges and other accidents that seriously affect people's production and life safety. Therefore, in the project, it is necessary to ensure that the quality of the concrete meets the requirements of the project. Therefore, aft...
