Abstract
The invention provides a steel slag and slag high-performance composite grout, which comprises the following raw materials by weight proportion: 0 to 60 portions of steel slag, 0 to 60 portions of granulated blast-furnace slag, 20 to 60 portions of sulphoaluminate cement, 0 to 50 portions of Portland cement, 2 to 8 portions of air entraining agent and excitant, 0.5 to 10 portions of slag activity excitant, 3 to 10 portions of antisettle agent, and 10 to 15 portions of high-performance expanding agent; and the raw materials are evenly mixed. The grout has better durability and wearing resistance, and can save resources and reduce the emission of waste at the same time to achieve the aims of protecting the environment and reducing the cost.
Description
Technical field
The present invention relates to a kind of cement based high-performance composite grouting material (calling the grouting material in the following text), used aggregate and adulterant are the waste of smelters such as slag, granulated blast-furnace slag, thereby formation aggregate and gelling material do not have the high-performance composite grout at interface.
Background technology
Entered since 21st century, China's iron and steel industry fast development has produced a large amount of discarded slags and granulated blast-furnace slag, has caused huge pressure to environment, and still with the speed increment in more than one hundred million tons of every year.The comprehensive utilization how effectively to solve waste reduces environmental stress, and it is turned waste into wealth is recycling economy and Sustainable development important topic.Slag and slag are used for making the grouting material, have advantages such as the resource of saving, cost are low, protection environment, good economic benefit and social benefit are arranged.At present mostly the grouting material exists that boundary strength is low, the defective of poor durability, simultaneously the mass consumption quartz sand resources.During particularly for consolidation of concrete structure, endurance issues shows particularly outstandingly.
For addressing the above problem; need mineral activity excitants such as development slag and slag; anti-sedimentation agent; adopt slag or granulated blast-furnace slag to replace the aggregate of quartz sand as the grouting material; adopt steel-making slag powder or slag powders equivalent substitution cement simultaneously; realize the no interfaceization of grouting material aggregate and gelling material, to realize performances such as high-durability, high-wearing feature.
Summary of the invention
The present invention is in order to solve the comprehensive utilization of waste; and problem such as high flow rate, grouting material poor durability, the boundary strength of quartz sand resources be low in the present commercially available grouting material, and a kind of steel slag and slag high-performance composite grout that adopts waste slag or granulated blast-furnace slag as aggregate is proposed.
Steel slag and slag high-performance composite grout of the present invention adopts slag or granulated blast-furnace slag as aggregate, the content that following raw materials according is arranged and measure by weight:
0～60 part in slag,
0～60 part in granulated blast-furnace slag,
20～60 parts of aluminosulfate cements,
0～50 part of silicate cement,
2～8 parts of bleed exciting agents,
0.5～10 part of mineral activity excitant,
3～10 parts of anti-sedimentation agent,
10～15 parts of high performance expansion admixture.
Above-mentioned raw materials mixes and gets final product.
In the above-mentioned grouting material, described mineral activity excitant is the mixture of alkaline, inorganic salts and alkaline polycarboxylate.
In the above-mentioned grouting material, it is 2000～10000 methyl condenses and the nano-silicon material material after compound that described anti-sedimentation agent is selected molecular weight for use.
In the above-mentioned grouting material, described bleed exciting agent is an aldehyde-ketone condensate, and the aldehyde-ketone condensate molecular weight is 8000～15000.
In the above-mentioned grouting material, described high performance expansion admixture is selected expansion agent for composite high performance grouting for use.
In the above-mentioned grouting material, described slag or granulated blast-furnace slag size are 0.005～5mm.
Steel slag and slag high-performance composite grout improves grouting material ageing resistance; the dominant mechanism of wear resistance is; employed slag; the granulated blast-furnace slag all has certain hydration activity; the secondary hydration reaction can take place with the effect of hydrated cementitious product; make the hydrated product of aggregate and the hydrated product of gelling material form fine and close netted overlap joint; the interface that causes original aggregate and gelling material is owing to interconnecting of hydrated product faded away; form the integral body at no interface; thereby improved the wear resistance of grouting material; the boundary strength of having eliminated original grouting material aggregate and gelling material is low, the defective of viscosifying power difference.In addition, behind the mineral admixture equivalent substitution cement, frost resistance, the impermeability of grouting material are improved, the chloride permeability coefficient reduces.Weather resistance, the wear resistance of grouting material are improved.Meanwhile also can consume a large amount of wastes, have and save resource, reduce cost, protect overall merit such as environment, meet the industry policy of national recycling economy and Sustainable development, will produce good economic benefit and social benefit.
