Abstract
The invention discloses a kind of half-flexible pavement cement mortar, the invention is gathered materials by cement, cellulose ether, polyacrylamide, poly carboxylic acid series water reducer, wood fibre, defoamer, silicon ash, flyash, and the component mixed preparing such as water is formed.Half-flexible pavement of the invention uses Portland cement, silicon ash with cement mortar, and flyash is Binder Materials so that the road surface after hardening has sufficiently high intensity, the half-flexible pavement after perfusion is possessed enough bearing capacitys.And add appropriate water reducer, wood fibre, the mobile performance for waiting and causing that the property of mortar is good of gathering materials that defoamer and a deciding grade and level are matched somebody with somebody makes that mortar is smooth, fully fills into Asphalt mix for open-graded friction course space.The cellulose ether of addition, polyacrylamide additive causes that mortar has good uniformity, occurs without the phenomenon such as layering and isolation, it is ensured that road face inside cement mortar is evenly distributed during construction, can be combined with compound well, improves the overall performance of half-flexible pavement.
Description
Technical field
The present invention relates to building materials field, and in particular to a kind of half-flexible pavement cement mortar.
Background technology
Half-flexible pavement is a kind of novel pavement that cement mortar is poured into Asphalt mix for open-graded friction course formation, its it is flexible with
Cement concrete pavement is rigid also superior to asphalt concrete pavement compared to more preferable, is also avoided while with their advantages
Their shortcoming.Therefore, half-flexible pavement is had started to using in the construction of high-grade highway at home.
The content of the invention
Present invention aim at, there is provided a kind of half-flexible pavement cement mortar, the technical solution adopted by the present invention is as follows：
A kind of half-flexible pavement cement mortar, it is characterised in that be mixed with by weight percentage by following components and formed：
Cement 20-50 parts
Cellulose ether 0.1-3 parts
Polyacrylamide 0.1-3 parts
Gather materials 20-40 parts
Poly carboxylic acid series water reducer 0.1-3 parts
Wood fibre 1-5 parts
Defoamer 0.1-2 parts
Silicon ash 5-10 parts
Flyash 5-15 parts
Water 10-30 parts.
Preferably, described cement is Portland cement.
Preferably, described cellulose ether is hydroxypropyl methyl cellulose ether of the viscosity in the mpa.s of 15-20 ten thousand.
Preferably, it is described to gather materials including quartz sand and rubble.
Preferably, described quartz sand by particle diameter be 30-50 mesh, 70-100 mesh, the quartz sand of 120-200 mesh is according to weight
Percentage is 1:1:2 mixing compositions, described rubble is 1-4mm by particle diameter, and the rubble of 5-10mm is 1 according to percentage by weight:1
Mixing composition.
The present invention is relative to the beneficial effect of prior art：Half-flexible pavement of the invention cement mortar is using common
Portland cement, silicon ash, flyash are Binder Materials so that the road surface after hardening has sufficiently high intensity, after making perfusion
Half-flexible pavement possesses enough bearing capacitys.And add appropriate water reducer, wood fibre, what defoamer and a deciding grade and level were matched somebody with somebody
The mobile performance for causing that the property of mortar is good such as gather materials, mortar smoothly, is fully filled into Asphalt mix for open-graded friction course space
In.The cellulose ether of addition, polyacrylamide additive causes that mortar has good uniformity, occurs without layering and isolation etc.
Phenomenon, it is ensured that road face inside cement mortar is evenly distributed during construction, can be combined with compound well, improves half-flexible pavement
Overall performance.
