The introduction of a chemical dispersion additive and the natural brucite short fibers to the cement mortar solves the contradiction between fiber splitting dispersion and the workability of the cement mortar, avoids the phenomena of fiber matting, aggregation and uneven dispersion when other reinforced fibers are applied to the cement mortar, makes full use of the reinforcement function of the short fibers, improves the breaking strength and tightness of the cement mortar, improves the cracking resistance of the cement mortar, and ensures the cement mortar not to bleed water without using a thickening agent, thus having better moisture retention and cohesiveness.
Description
Technical field
The present invention relates to a kind of material of construction, particularly brucite fiber reinforced finished cement mortar material.
Background of invention
The commodity sand-cement slurry comprises wet mixing mortar and dry-mixed mortar, is the commodity-type New Building Materials of being produced by professional production factory.Compare series of advantages such as that the commodity sand-cement slurry has is best in quality and stable, with low cost, great variety of goods, construction civilization, work efficiency raising with the sand-cement slurry that traditional working-yard makes.Along with the issuing and implementation of commodity mortar national sector standard, the commodity sand-cement slurry can be rapidly developed.
But similar to traditional sand-cement slurry performance, the commodity sand-cement slurry remains a kind of poor toughness, hard brittle material inhomogeneous, easy to crack, and it is low to exist tensile pressure ratio, and is dry-shrinkage deformed big, shortcomings such as impermeability, splitting resistance, corrosion-resistant.In recent years, along with the construction work development of modernization, particularly cohesive strength, resistance to cleavage, impermeability etc. are all had higher requirement to mortar performance.The tradition cement mortar material is difficult to satisfy the more and more higher actual requirement of engineering.
Mixing each fiber material is one of effective ways that improve sand-cement slurry toughness and splitting resistance.Fiber commonly used has synthetic organic fibre, glass fibre, steel fiber, carbon fiber etc. in mortar at present.But these fibers or cost are too high, or being difficult to construction mixes, and influences it and applies.
In addition, in order to improve the construction workability of commodity sand-cement slurry, add some admixtures in the composition of being everlasting,, the cost of mortar is improved as water-retaining admixture etc.
Summary of the invention
The purpose of this invention is to provide a kind of with natural brucite staple fibre enhanced commodity cement mortar material.This brucite staple fibre enhanced sand-cement slurry has advantages such as intensity height, mixture water-retentivity and cohesiveness are good, splitting resistance is good, with low cost.
Technical scheme of the present invention is achieved in that
The present invention is made up of cement, sand, water, brucite fiber and dispersion admixture, wherein brucite fiber is the staple fibre of 6 grades and following grade, quality consumption in mortar is the 3-6% of cement amount, disperseing admixture quality consumption in the commodity sand-cement slurry is the 1.0-1.8% of cement amount, the quality consumption of sand is 1.0-7.0 a times of cement amount, and the quality consumption of the water yield is 0.35-1.6 a times of cement amount.
Disperse admixture to be made up of naphthalene series high-efficiency water-reducing agent, sulfamate water reducer or sulfonated lignin water reducer, alcohol and urea, the quality consumption is respectively 0.7-1.2%, 0.15-0.30%, 0-0.25%, the 0-0.25% of cement amount.
The manufacture craft of mixing the commodity sand-cement slurry of doing of the present invention is: packing after cement, sand, brucite staple fibre are stirred in forced mixer, and when site construction, add water again and disperse admixture to stir.The manufacture craft of wet-mixing commodity sand-cement slurry is: cement, sand, brucite fiber, dispersion admixture and water are stirred in forced mixer to get final product.
Brucite fiber be a kind of be the natural mineral fiber of main component with the magnesium hydroxide, be the advantage Mineral resources of China.Brucite fiber has excellent mechanical property and water-dispersion performance, compare with the existing various fortifying fibres that are used for sand-cement slurry, brucite fiber have with low cost and with obvious advantages such as the cement bonding force is strong.
6 grades and following grade brucite fiber are low-grade brucite staple fibres, and they mostly are the tankage of mine ore dressing processing, and staple length is generally less than 5mm.Compare with the brucite macrofiber, 6 grades and following grade brucite fiber are cheap.Because fiber is too short, at present mainly as industrial filler, and can not use as strongthener.
The present invention carries out chemistry by the chemical dispersion admixture to the natural brucite staple fibre and splits branch, can make the Fibre diameter refinement reach nano level, has improved the length-to-diameter ratio of staple fibre, thereby can bring into play the enhancement of fiber effectively, has increased the using value of fiber.Compare with macrofiber, the brucite staple fibre mixes in sand-cement slurry easily, and does not have mat-ups, the group of beating that other fiber occurs in application, disperse phenomenons such as irregular.Fiber has bigger specific surface area after splitting branch, and its water-absorbent is increased, and can influence the workability of sand-cement slurry.The present invention combines the chemical dispersion technology of fiber with the diminishing technology of cement, by selecting suitable fiber dispersion admixture and cement water reducing agent, solved rightly that the fiber of fiber applications in sand-cement slurry splits that branch disperses and the workability of sand-cement slurry between contradiction.
Because the application of chemical dispersion admixture helps promoting the homodisperse of fiber in sand-cement slurry, makes fiber consumption just can bring into play enhancement under situation seldom, helps the cost of controlling fiber sand-cement slurry.
Because the adding of chemical dispersion admixture and brucite staple fibre, increased the endergonic ability of mortar, the folding strength and the toughness of sand-cement slurry have been improved, improved the resistance to cleavage of sand-cement slurry, also make sand-cement slurry have water-retentivity and cohesiveness preferably simultaneously, needn't add water-keeping thickening material again, thereby reduce the production cost of mortar.
Brucite fiber reinforced finished cement mortar can be applied to a plurality of engineerings field, as building, tunnel, airport, road surface, bridge floor etc. build by laying bricks or stones, plaster and ground surface works in.
