Abstract

The invention relates to a building material, in particular to a multi-row-hole self-insulation lightweight fly ash block. The multi-row-hole self-insulation lightweight fly ash block is a cuboid lightweight fly ash block with uniformly distributed through holes. The lightweight fly ash block is prepared by taking Portland cement as a cementing material and taking fly ash, coarse ash, ceramsite or slag, pumice, pearlite or vermiculite, sawdust, polyphenyl granules, a building adhesive, a humectant and additives as fillers through the processes of diluting the materials with water, blending the materials, mixing, stirring, extruding and curing. After the multi-row-hole self-insulation block structure is matched with a lightweight composite fly ash material, the insulation property, lightweight property, heat and sound insulation properties, fireproof property, durability and other properties of the block are greatly improved, the traditional clay bricks and aerated blocks and the traditional external wall insulation method are replaced, and the national building energy saving requirement is completely met.

Description

The many hole self-heat insulating building blocks of light flyash

Technical field

The present invention relates to constructional materials, specifically the many hole self-heat insulating building blocks of a kind of light flyash (also claiming to lay bricks).

Background technology

At present in building field, its exterior wall or interior wall adopt the building block masonry structure of (also claiming to lay bricks) usually, it is main that masonry is roughly sintered clay brick or fly ash aerated, not only waste resource, consume the energy, contaminated environment, exist simultaneously the deficiencies such as insulation, lightweight, heat insulation, sound insulation value, and the building energy conservation aspect can't reach national requirements, and existing sintered clay brick or fly ash aerated are applied to exterior-wall heat insulation, can't satisfy insulation and the integrated requirement of building structure, prevent fires and aspect durability, also existing huge hidden danger.

Summary of the invention

The objective of the invention is the problems referred to above of existing for prior art, a kind of have sharp useless, energy conservation, low production cost are provided, have simultaneously insulation, lightweight, heat insulation, sound insulation, fire prevention, durable many hole self-heat insulating building blocks of light flyash.

The present invention can reach by following technical solution:

The many hole self-heat insulating building blocks of light flyash are that the light flyash building block at cuboid is evenly equipped with through hole.This light flyash building block is take portland cement as cementitious material, with flyash, and cinder slag, haydite or slag, float stone, perlite or vermiculite, sawdust, granular polystyrene, building adhesive, NMF and additive are filler, and dilute with water is in harmonious proportion, and is formulated through mixing, stirring, extruding and maintenance; Its through hole cross section is rectangle, and the spread pattern of through hole is that multistage, multilayer parallel are arranged alternately.

The weight ratio of described each composition of light flyash building block is portland cement 6-30%; Flyash 10% ~ 40%; Cinder slag 20 ~ 50%; Haydite or slag, float stone 5% ~ 30%; Perlite or vermiculite 0.5% ~ 2%; Sawdust 0.5% ~ 3%; Granular polystyrene 0.1% ~ 0.5%; Building adhesive 0.02% ~ 0.1%; NMF 0.01% ~ 0.1%; Additive 0.01% ~ 0.1%; Surplus is water; Building adhesive wherein comprises a kind of of 107,108,801 glue for building, and NMF is the concrete moisture retention agent, and additive comprises one or more in the reinforcement of concrete accelerating admixture, reinforcing agent, corrosion inhibitor, the antifreezing agent.

Former and later two corresponding openends of described through hole have the curved shrinkage cavity structure of an end at least, the spread pattern of its through hole is that one deck is the above complete through hole of N and the successively parallel mutual arrangement of half-open discharge hole of the individual complete through hole of another layer N-1 and both sides, N wherein is the integer greater than 1, the curved structure of through-hole side wall.

Many hole self-heat insulating building blocks structure of the present invention is that there is the hole wall interval in every round hole with the block of rectangular through hole and vertically staggered half through hole, at the two ends of block region division open vertical hole is arranged on one side, and every round hole is staggered.And after building block first row and last row's through-hole wall mounts aluminium foil, be equivalent to increase the anti-heat radiation layer, effectively stop the radiation heat transfer in the hole, thereby increase the thermal resistance of building-block, improve the heat-insulating property of building-block, reduce the heat consumption by building.After building by laying bricks or stones, vertically hole is interlaced, has reduced vertical cold bridge, has improved heat insulation effect.After particularly adopting this structure of lightweight composite fly ash material fit, effectively reduced the raw material use amount, reduced own wt, the vertical hole of many rows has improved the thermal resistance of masonry, the in addition less coefficient of thermal conductivity of raw material, make it the performances such as insulation, lightweight, heat insulation, sound insulation, fire prevention, durability and greatly improve, substituted traditional loam brick, aerated blocks and traditional external wall thermal insulation method, satisfied the building energy conservation requirement of country's " living energy-conservation 65% ", " public energy-conservation 50% " fully.
