Description
Technical field
The present invention relates to construction material, specifically a kind of zigzag lightweight concrete heat insulating composite building block, match somebody with somebody
Side and preparation method thereof.
Background technology
The urban construction theory of " green, energy-saving and environmental protection " was progressively popularized in recent years, building energy conservation requirement more and more higher, entirely
State's some areas building energy saving rate by original 65% improve till now 75%, promote insulating wall material of new generation quick
Growth and development.But existing insulation blocks generally existing autogenous shrinkage is big, moisture content is high, sensitive to temperature, sedimentation change,
So that some many defects of concrete insulation blocks wall are progressively exposed：As wall crazing, seepage, wall skin come off, saved not
Up to standard, wall overall durability poor-performing etc., as quality problem main in architectural engineering.
In order to solve the problems, such as above-mentioned wall quality, we have made intensive studies and divided from material to construction to construction wall
Analysis, it is found that insulation blocks cavity body material and its formula play a key effect wherein.The cavity body of insulation blocks is typically mixed
Soil is coagulated, the heterogeneous material that it is made up of aggregate, binder materials, gas, moisture etc. is cementing to be formed.Insulation blocks itself ftracture
Main cause be in course of hardening, produce cubic deformation, such as " the wet drying shrinkage that rises ", " chemical shrinkage ", it is this change
Shape causes the uneven of Volume Changes due to the not homogeneous of the various components of concrete：Binder materials shrinks larger, and aggregate shrinks very
Small, their thermal coefficient of expansion is different, can still be expanded after the material water suction after drying shrinkage, material can be sent out again after dehydration
Life is dry-shrinkage deformed, so circulation, and cubic deformation freely, does not produce restraint stress, thereby results in crack and damage.
Concrete density, thermal conductivity factor, the wall assembled deadweight, three are proportionate.Normal concrete and its insulation are built
Block product thermal resistance is small, can not meet building energy conservation requirement, and influence anti-seismic performance.If the grading of aggregates used in production
It is unreasonable, building block outer wall leakiness, infiltration can be caused, does not reach seepage resistance demand, wall durability is reduced.
In summary, how to realize heat insulation building block building energy conservation standard and can meet building block all other indexs will
Ask, it can be the technical problem that presently, there are to improve wall cracking resistance, water permeability resistance.
The U of Patent No. CN 204185992 patent document discloses a kind of combined lightweight aggregate concrete heat insulation building block,
Including cavity body and insulation material, cavity body is the hollow right angle hexahedron that combined lightweight aggregate concrete one-piece casting is molded, empty
The outer wall of cavity is to be symmetrically arranged with two middle ribs, cavity to be filled with light porous insulation on the inside of rectangular box, its two waist
The core body of material.The triangle that middle rib is isosceles triangle or drift angle is fillet, base and the outer wall of triangle are connected as a single entity.Gently
Matter porous insulation material is polystyrene foam or polyurethane foam.It is whole but the technical scheme has insulation blocks unit weight height
Body low intensity, easy to crack, breakage rate is big, the shortcomings of anti-permeability performance is poor.
The content of the invention
