Abstract

The invention discloses a flexible reinforced fiber concrete. The concrete is prepared from the following raw materials in parts by weight: 110-130 parts of ordinary Portland cement, 10-15 parts of high-iron aluminophosphate cement, 25-30 parts of modified waste rubber particles, 5-10 parts of polyolefin elastomer, 3-6 parts of flotation deinking slag fibers, 3-5 parts of modified sepiolite fibers, 10-20 parts of silicon carbide powder, 5-10 parts of bamboo fiber powder, 10-15 parts of a polycarboxylate superplasticizer, 3-5 parts of magnesium fluosilicate, 10-15 parts of slag powder, 3-7 parts of coal ash, 160-170 parts of sand, 460-480 parts of pebbles and 50-60 parts of water. The invention also discloses a preparation method of the flexible reinforced fiber concrete. The flexible reinforced fiber concrete disclosed by the invention has the characteristics of good deformability, high toughness, high strength and good adhesive property, and the expansion stress of the concrete is absorbed by utilizing the elastic characteristics of the modified waste rubber particles and the polyolefin elastomer, so that the overall volume stability of the concrete is good; and the concrete is matched with other materials, so that the overall flexibility of the concrete is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of concrete, and in particular relates to a flexible reinforced fiber concrete and a preparation method thereof. Background technique [0002] Economic development is inseparable from road construction. "If you want to get rich, you must first build roads." This shows the importance of road construction to my country's economic construction. However, economic development will inevitably increase road traffic volume. There is a "push-pull relationship" between the two. . Judging from the current use of roads in our country, in addition to the large traffic volume, long-term heavy loads and overloads have become the characteristics of contemporary road use. Cement concrete is a kind of artificial stone made of cement cementitious material, granular aggregate (also known as aggregate) and water according to a certain proportion, uniformly stirred, densely formed, cured and hardened. As a pavement material, cem...
