Embodiment Construction

[0023] The rubber aggregate grouting material of the present invention includes the following components: 4 to 8 parts of rubber aggregate, 65 to 87 parts of sand, 55 to 85 parts of cement, 4 to 10 parts of admixture (of which fly ash 2 ~5 parts, 1~2 parts of silicon powder, 1~3 parts of mineral powder), 20~32 parts of water, 4~12 parts of admixtures (including 3~10 parts of expansion agent and 1~2 parts of superplasticizer), The above-mentioned parts are all parts by weight. The rubber aggregate may be waste passenger car tires, truck tires, heavy truck tires, tractor tires, waste tires of rickshaw tires, adhesive tapes, waste rubber hoses, rubber shoes, wires and cables, industrial rubber parts, or waste rubber from rubber sheets. At least one of the products. The rubber aggregate is preferably calculated by weight percentage, the moisture content is less than 1.0%, the ash content is less than 5.0%, the acetone extract is less than 15.0%, and the metal content is less than 0.1%...

Abstract

The invention discloses a rubber crumbs grouting material, which comprises the following components by weight proportion: 4-8 parts of rubber crumbs, 65-87 parts of sand, 55-85 parts of cement, 4-10 parts of admixture, 20-32 parts of water and 4-12 parts of additive; wherein, the admixture consists of 2-5 parts of fly ash, 1-2 parts of ganister sand and 1-3 parts of powered ore while the additive consists of 3-10 parts of expanding agent and 1-2 parts of super plasticizing agent. The rubber crumbs grouting material of the invention is characterized by better fluidity, longer operation time, expansion rate not less than 0.02%, trabecular ductility factor not less than 1.1 and high compressive strength; can utilize waste materials and lower the cost.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to rubber aggregate grouting. Background technique [0002] Grouting material is widely used in the installation of equipment in electric power, machinery, metallurgy, chemical, petroleum, construction and other industries. It is suitable for the secondary grouting of large and medium-sized equipment, anchoring of anchor bolts, slab grouting, engineering repairs and emergency repairs in the construction of early strength, no shrinkage and high fluidity requirements. [0003] Grout is generally a multiphase composite material composed of cement hydration products, river sand, free water and pores. Its basic composition principle is to use the active ingredients in cement, such as tricalcium silicate, dicalcium silicate, and aluminum. Ingredients such as tricalcium acid react chemically with water to form a cement with a certain strength, namely cement stone. The cement stone an...
