Abstract
The invention discloses a kind of controllable temperature concrete, its is raw materials used to include by weight：70 80 parts of binding material, 10 15 parts of chopped carbon fiber, 0.5 0.8 parts of copper facing steel fibre, 0.8 1.0 parts of rubber powder, 0.1 0.3 parts of water reducer, 0.05 0.10 parts of defoamer；Its preparation method is specifically after above-mentioned each raw material is mixed with aggregate plus water is mixed thoroughly, obtained through pouring, conserving.Gained controllable temperature concrete of the invention has self-regulating performance, and the effect that cools under the high temperature conditions is notable, under cryogenic with heat storage function, suitable for expressway construction, can effectively extend the service life of highway.
Description
Technical field
The invention belongs to concrete material technical field, and in particular to a kind of controllable temperature concrete.
Background technology
At present, many highways are after operation is built up, because the change of weather and environment temperature can be such that road surface produces not
With the high/low temperature disease of degree, the service life on road surface is greatly shortened, causes many highways to enter overhaul or transformation in advance
Phase, this not only causes substantial amounts of economic loss, also non-renewable resources is greatly consumed.
The content of the invention
It is an object of the invention to provide a kind of controllable temperature concrete, and it has self-regulating performance, dropped under the high temperature conditions
Warm effect is notable, under cryogenic with heat storage function, suitable for expressway construction, can effectively extend making for highway
Use the time limit.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of controllable temperature concrete, its is raw materials used to include by weight：Binding material 70-80 parts, chopped carbon fiber 10-
15 parts, copper facing steel fibre 0.5-0.8 parts, rubber powder 0.8-1.0 parts, water reducer 0.1-0.3 parts, defoamer 0.05-0.10 parts.
The binding material is Portland cement；
The water reducer is polycarboxylate water-reducer；
The defoamer is polyethers defoamer.
The preparation method of the controllable temperature concrete is by binding material, chopped carbon fiber, copper facing steel fibre, rubber powder, diminishing
After agent, defoamer mix with aggregate plus water is mixed thoroughly, through pouring, conserving the obtained controllable temperature concrete.
The aggregate includes rubble, Yuhuatai colorful pebble, granite and crystal；The weight ratio of itself and binding material is 1.7-2.0:1；Institute
It is 0.35-0.40 with the weight of water and binding material ratio:1.
The remarkable advantage of the present invention is：The present invention produces material by the way that chopped carbon fiber, copper facing steel fibre are added
Pyroelectric effect, so as to carry out temperature control to concrete according to external environment condition change, make its effect that cools under the high temperature conditions notable,
There is heat storage function, and its easy construction, cracking resistance is good, and quick-drying is hard soon, can suitable for expressway construction under cryogenic conditions
Extend highway service life 3-5.Meanwhile the controllable temperature concrete can also be used for building, be advantageous to make building
It is cool in summer and warm in winter inside thing, reach the purpose of energy-conserving and environment-protective.
