Abstract
The invention discloses a high-toughness building material. The building material is prepared from the following ingredients in percentages by weight: 20-25% of cement, 60-65% of blend, 5-10% of fiber material and 5-10% of dispersant, wherein the fiber material mainly includes a polyvinyl alcohol fiber, a polyethylene fiber and a carbon fiber; the dispersant mainly comprises silica fume and methylcellulose; the methylcellulose takes 0.01-0.2% of the total weight of dispersant. The fiber material and the dispersant are added into the high-toughness building material disclosed by the invention; the dispersant enables the fiber material to be uniformly dispersed so as to better exert the enhancement action and crack resistance action of the fiber; a prepared concrete product is quite strong in toughness, improved in mechanical performance, and obviously improved in interfacial deformation resistance capacity; the possibility of concrete crack and fracture in disasters such as an earthquake is reduced.
Description
Technical field
The present invention relates to building material technical field, especially a kind of high tenacity material of construction.
Background technology
Material of construction is the basic substance of construction work, and buildings needs to use various materials in constructing from the agent structure to decorations.Concrete is as most widely used material of construction; its main component comprises cement; adulterant and aggregate; adding water stirring post-hardening forms; it is simple to have technology; advantages such as fire resistance; but it is a kind of hard brittle material; tension and bending strength are low; deformability is little; poor toughness; concrete low toughness makes structure in the variable cross-section position and steel/and positions such as concrete hybrid structure node may cause the catastrophic failure that happens suddenly owing to stress concentration; especially under the earthquake load effect; therefore the premature failure of protective layer also usually can take place in concrete structure, thereby causes the anti-seismic performance of structure significantly to reduce.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the technical problem of toughness of concrete deficiency in the prior art, a kind of high tenacity material of construction is provided, effectively improve concrete toughness, reduce the probability of cracking and fracture.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high tenacity material of construction, comprise cement, adulterant, filamentary material and dispersion agent, described filamentary material mainly comprises polyvinyl alcohol fiber, polyethylene fiber peacekeeping carbon fiber, dispersion agent mainly comprises silicon ash and methylcellulose gum
The weight ratio of each component is as follows:
Cement 20-25%
Adulterant 60-65%
Filamentary material 5-10%
Dispersion agent 5-10%
Wherein methylcellulose gum accounts for the 0.01-0.2% of gross weight in the dispersion agent.
Further, polyvinyl alcohol fiber accounts for 1-3%, the polyethylene fibre 0.5-1.0% of gross weight, the 3.5-8.5% that carbon fiber accounts for gross weight in the described filamentary material.
Further, the length of described polyvinyl alcohol fiber is 10-15mm, and diameter is 0.03-0.05mm.
Further, the length of described polyethylene fibre is 10-15mm, and diameter is 0.03-0.05mm.
Further, described carbon fiber adopts asphaltic base or PAN base carbon fibre, length 3-10mm, diameter 8-10mm.
A kind of method of producing above-mentioned high tenacity material of construction has following steps: earlier cement is dropped into whipping appts; Open whipping appts, drop into each component by concrete mix and stir; Methylcellulose gum is scattered in the water stirs, after waiting to dissolve solution added in the whipping appts and stir, add water reducer at last, be stirred to the required slump and get final product.
The invention has the beneficial effects as follows, high tenacity material of construction of the present invention, add filamentary material and dispersion agent, dispersion agent can make filamentary material be uniformly dispersed, thereby better brings into play enhancing, the action of crack arrest of fiber, and the concrete product of making has stronger toughness, improve mechanical property, significantly improve the ability of interface resistance to deformation, when disasters such as generation earthquake, the probability of concrete generation cracking and fracture reduces.
