Problems solved by technology

[0002] Improving the quality of waterproofing, plugging, and water-stopping projects in buildings and special projects is one of the goals pursued by construction waterproofing engineering scientists and technicians for many years; the inorganic plugging materials currently on the market generally add a certain proportion of water glass to ordinary cement, etc. It is made of inorganic fast-setting materials and compounded with Portland cement by using ferric chloride, expansion agent, water reducer, silica fume, fly ash and various slurries. This kind of plugging material has low early strength , easy to shrink, easy to crack, corrosion resistance, poor durability; inconvenient construction, difficult operation, unsatisfactory waterproof effect
And organic plugging materials, such as epoxy resin, etc., generally contain certain toxicity, and the cost is extremely high

Abstract

The invention discloses a highly efficient plugging material, which adopts the following components by weight percent: 86-92% of sulphate aluminum cement clinkers, 4-8% of anhydrite, 3-6% of lime stones, 0.02-0.05% of plasticizing agent, 0.06-0.15% of hardening accelerator and 0.12-0.15% of short and thin polypropylene fiber. The highly efficient lost circulation material has the characteristics of fast solidification, high hour strength, strong adhering capability, high anti-seepage grade, lower cost, convenient construction operation, safety and environment protection.

Description

technical field [0001] The invention belongs to a high-efficiency leak-stopping material used for building and engineering waterproofing and leak-stopping. Background technique [0002] Improving the quality of waterproofing, plugging, and water-stopping projects in buildings and special projects is one of the goals pursued by construction waterproofing engineering scientists and technicians for many years; the inorganic plugging materials currently on the market generally add a certain proportion of water glass to ordinary cement, etc. It is made of inorganic quick-setting materials and compounded with Portland cement by using ferric chloride, expansion agent, water reducing agent, silica fume, fly ash and various slurries. This kind of plugging material has low early strength , easy to shrink, easy to crack, corrosion resistance, poor durability; inconvenient construction, difficult operation, and unsatisfactory waterproof effect. And organic plugging materials, such as e...
