Abstract
Provided are antifreezing anti-cracking thermal insulation mortar containing rice hull powder and a preparation method thereof. The antifreezing anti-cracking thermal insulation mortar is characterized by comprising, by weight parts, 100-200 parts of Portland cement, 25-30 parts of magnesite, 15-20 parts of diatomaceous earth, 2-5 parts of compound additive, 3-5 parts of boron nitride, 2-4 parts of latex, 0.1-0.3 part of antifreezing agent, 0.2-0.5 part of polycarboxylate superplasticizer and 100-200 parts of water. 10-20 weight parts of rice hull powder is further added into the raw material components, and the rice hull powder has a granularity of below 3 mm. The antifreezing anti-cracking thermal insulation mortar has the advantages of being high in intensity, good in toughness, resistant to cracking and seepage and high in stability and the like, the problems of cracks, crispness and water seepage resulting from repeated melting and freezing of concrete caused by temperature changes can be effectively solved, concrete intensity, toughness and stability indexes are improved, and the antifreezing anti-cracking thermal insulation mortar is particularly suitable for northern high and cold areas.
Description
Technical field
The present invention relates to building material field, particularly relate to a kind of antifreeze anti-cracking heat insulation mortar containing powdered rice hulls and
Preparation method.
Background technology
Concrete mortar is widely used in the engineerings such as bridge, building, power station, not only needs higher intensity, toughness
And stability requirement, and must have self certain water resistance, at northern area, in addition it is also necessary to possess cold-resistant freeze proof simultaneously
Performance.Especially extremely frigid zones, difference variation is big, concrete easily occur through the most repeatedly freezing, after melting process crackle,
Becoming crisp, infiltration phenomenon, the index such as its intensity, toughness and stability is severely impacted.
Rice husk is a kind of discarded crops, if can apply in mortar for building, and is equipped with and has protection against the tide, resistance
Combustion, the additive of heat insulation function, will well play the effect of twice laid.
Summary of the invention
The present invention provides a kind of antifreeze anti-cracking heat insulation mortar containing powdered rice hulls and preparation method thereof, has intensity high, tough
Good, the premium properties of freedom from cracking, antiseep of property, can effectively solve owing to difference variation causes what concrete thawing repeatedly caused to split
Stricture of vagina, change shortcake, infiltration phenomenon, improve its intensity, toughness and stability indicator.
In order to achieve the above object, the present invention realizes by the following technical solutions:
A kind of antifreeze anti-cracking heat insulation mortar containing powdered rice hulls, including the component of following weight: portland cement
100-200, magnesia 25-30, kieselguhr 15-20, compound additive 2-5, boron nitride 3-5, latex 2-4, antifreezing agent 0.1-0.3,
Polycarboxylate water-reducer 0.2-0.5；Water 100-200；Described raw material components is additionally added powdered rice hulls 10-20 weight portion, described
Powdered rice hulls be granularity be the powdered rice hulls of below 3mm；
Described compound additive is: montmorillonite 2 0-30, sodium sulfate 5-10, sucrose 5-10, cellulose ether 2-3, bentonite
2-3, boric acid 2-3, mix homogeneously is made.
Described antifreezing agent is the one of sodium nitrite, nitrite, calcium chloride, ethylene glycol, calcium nitrite, carbamide.
The preparation method of a kind of described antifreeze anti-cracking heat insulation mortar containing powdered rice hulls, except portland cement, compound interpolation
Beyond agent, described raw material ratio by weight being stirred, be eventually adding portland cement, compound additive, mixing is all
Even make.
Compared with prior art, the invention has the beneficial effects as follows:
This concrete has intensity height, good toughness, freedom from cracking, antiseep, stability advantages of higher, can effectively solve due to
Difference variation causes crackle that concrete thawing repeatedly causes, becomes crisp, infiltration phenomenon, improves the intensity of concrete, toughness and steady
Qualitative index, is particularly suitable for cold area in north.
