Multi-component concrete surface reinforcing agent and reinforcing method thereof

Abstract

The invention provides a multi-component concrete surface reinforcing agent and a construction method thereof. The reinforcing agent is prepared from a component A, a component B and a component C. The component A comprises, in parts by weight, 10-15 parts of sodium alginate, 0.5-3 parts of fluorocarbon surfactant, 1-3 parts of nano silicon dioxide and water supplementing to 100 parts; the component B comprises, in parts by weight, 1 to 5 parts of fluorocarbon surfactant, 10 to 20 parts of soluble silicate, 10 to 15 parts of soluble fluosilicate, 0.1 to 2 parts of water reducing agent and water supplementing to 100 parts; and the component C comprises, in parts by weight, 5-10 parts of soluble calcium salt, 0.5-3 parts of a fluorocarbon surfactant and water supplementing to 100 parts. Sodium alginate permeates into the deep layer in the concrete and reacts with Ca<2+> to generate an insoluble gel system to block pores in the deep layer of the surface; soluble silicate and fluosilicatepermeate and react with Ca<2+> to generate gel of a cross-linked structure, pores in the surface layer of the surface are blocked, concrete is compacted fundamentally through cooperation of two timesof blocking, invasion of water, oil and other corrosive substances is effectively inhibited, and the durability of the concrete can be greatly improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a multi-component concrete surface reinforcing agent and a reinforcing method thereof. Background technique [0002] Cement-based materials are currently the most widely used building materials. Whether it is high-rise buildings or high-speed, high-speed rail, water conservancy and hydropower, industrial and civil buildings, etc., cement-based building materials are inseparable. Phenomena such as dust, exposed rocks, etc. are very common, and the deterioration of surface performance seriously affects its performance and durability, resulting in a greatly shortened service life of the material, which will inevitably lead to repair and reconstruction of a large number of construction projects, and further increase the consumption of cement-based materials. It is a great waste of resources, so the performance of the surface layer has become one of the important factors ...
