Abstract
The present invention provides a kind of highway wood fibre enhancing cement, and raw material is by weight are as follows: 200 ~ 255 parts of white cement, 60 ~ 95 parts of dicalcium powder, 72 ~ 85 parts of silicon ash, 80 ~ 120 parts of diatomite, 55 ~ 74 parts of fine sand, 20 ~ 32 parts of rubber powder, wood fibre 28 ~ 52,25 ~ 50 parts of steel fibre, 5 ~ 10 parts of polycarboxylate water-reducer.The phenomenon that intensity that the wood fibre mixture that the present invention uses has is preferable, prevents high cracking performance, water retention property height, adhesive force from increasing, and reduces skinning inside slurry.
Description
Technical field
The present invention relates to engineering material field of material technology, and in particular to a kind of highway wood fibre enhancing cement.
Technical background
Currently, be widely used in the fields such as concrete mortar, plastering, wood pulp sponge, asphalt roads, to preventing coating from opening
Split, improve water-retaining property, improve production stability and construction conformance, increase intensity, enhancing have to the adhesive force on surface etc.
Good effect.Its technical role is mainly: thixotroping, protection, absorption, carrier and filler.
Due to the capillarity of fibre structure, the moisture of internal system is promptly transferred to pulp surface and interface,
So that the uniform moisture distribution inside slurry significantly reduces skinning.And adhesion strength and surface strength are significantly improved,
This mechanism also due in drying process the reduction of tension and obviously play the role of cracking resistance.Wood fibre dimensional stability and heat
Stability plays the role of good thermal-insulating and anti-cracking in thermal insulation material.The wood fibre that existing highway cement concrete uses
Mixture performance in terms of splitting resistance, water-retaining property, adhesive force is lower.
Therefore, it is necessary to a kind of lightweights of the wet or dry dimensional stability of improvement with the product modified better than typical density
Highway material and method for manufacturing it.In addition, very preferably the material also has good waterproof in some applications
Property, good heat insulating ability and high temperature dimensional stability.
