Abstract
The invention discloses a self-insulation composite building block, which comprises the following materials in mass ratio: 240-260kg of cement, 64-78kg of coal ash, 20-36kg of coal cinder, 300 kg or 500 kg or 700kg of sand, 60 kg or 70kg of rice husk, 30 kg or 70kg of vitrified micro bubble, 220-255kg of water and 25.28kg of polrvinyl chloride foam. The self-insulation composite building block provided by the invention is low in manufacture cost, and the compressive strength can be substantially improved while the insulation performance is favorably guaranteed.
Description
Technical field
The present invention relates to a kind of self-heat conserving composite block, especially add the self-heat conserving composite block that rice husk is arranged.
Background technology
The tradition thermal insulation mortar comprises cement, flyash, cinder, sand, glass bead, water, polyvinyl chloride foam, and its reflect heat effect is relatively poor, causes heat insulation effect general, and ultimate compression strength is also relatively poor.
Summary of the invention
Technical problem to be solved by this invention provides a kind of self-heat conserving composite block, and this building block cheap for manufacturing cost can increase substantially ultimate compression strength in the heat-insulating property ensureing preferably.
For this reason; Self-heat conserving composite block provided by the invention; Comprise cement, flyash, cinder, sand, rice husk, glass bead, water, polyvinyl chloride foam, above-mentioned materials quality proportioning is cement 240-260, flyash 64-78, cinder 20-36, sand 300 or 500 or 700, rice husk 60 or 70, glass bead 30 or 70, water 220-255, polyvinyl chloride foam 25.28.
In self-heat conserving composite block provided by the invention; Added rice husk, the inside and outside wall of rice husk is curved, has good heat reflection effect; And after a large amount of rice husks adding building blocks; The multilayer rice husk is layering and can further improve the heat reflection effect, because the material that adopts is a rice husk with low cost, thereby can reduce the material cost of building block.And through after the mixing of above-mentioned materials proportioning the intensity of building block being increased substantially.
Embodiment
Self-heat conserving composite block provided by the invention comprises cement, flyash, cinder, sand, rice husk, glass bead, water, polyvinyl chloride foam; Above-mentioned materials quality proportioning is cement 240-260, flyash 64-78, cinder 20-36, sand 300 or 500 or 700, rice husk 60 or 70, glass bead 30 or 70, water 220-255, polyvinyl chloride foam 25.28; Water consumption when water is mixing; Polyvinyl chloride foam among the present invention is not to adopt and the other materials method of mixing, but behind block forming, directly inserts in the hole of building block.The strength of cement grade is 42.5 in the building block, and flyash is secondary.
Tabulate the technique effect of self-heat conserving composite block provided by the invention below with experimental data:
Quality of materials unit is in the form: kilogram
In above-mentioned experimental data, the thermal conductivity of traditional aerated insulation block or haydite insulation blocks is generally 0.16 to 0.20
W/ (m ℃), and intensity all is 3.5-5.0Mpa, thermal conductivity all is lower than or approaching traditional building block thermal conductivity Schwellenwert 0.16 in the above-mentioned list of experiments
W/ (m ℃)And intensity all reaches more than the 4Mpa; Therefore insulation blocks provided by the invention obviously has thermal conductivity and all is lower than traditional insulation blocks, and the performance that increases substantially of ultimate compression strength, therefore can be used as the novel architecture environment-friendly materials; When improving heat-insulating property, increase substantially the intensity of buildings.
Enumerate three proportioning cases that performance is especially superior below:
Case 1,260 kilograms of said cement, 65 kilograms in flyash, 26 kilograms of cinders, 500 kilograms in sand, 70 kilograms on rice husk, 70 kilograms of glass beads, 230 kilograms in water, 25.28 kilograms of polyvinyl chloride foams.The material that adopts said ratio to mix, after the compression shock moulding, ultimate compression strength 8.8Mpa, thermal conductivity are 0.141
W/ (m ℃)
Case 2,255 kilograms of cement, 64 kilograms in flyash, 32 kilograms of cinders, 700 kilograms in sand, 60 kilograms on rice husk, 30 kilograms of glass beads, 225 kilograms in water, 25.28 kilograms of polyvinyl chloride foams.。The material that adopts said ratio to mix, after the compression shock moulding, ultimate compression strength 7.0Mpa, thermal conductivity are 0.151
W/ (m ℃)
Case 3,240 kilograms of cement, 72 kilograms in flyash, 36 kilograms of cinders, 300 kilograms in sand, 70 kilograms on rice husk, 70 kilograms of glass beads, 250 kilograms in water, 25.28 kilograms of polyvinyl chloride foams.The material that adopts said ratio to mix, after the compression shock moulding, ultimate compression strength 9.3Mpa, thermal conductivity are 0.1552
W/ (m ℃)
From above-mentioned three kinds of cases, can observe and draw; Through compression shock moulding after the mixing of above-mentioned multiple material; Can ensure that compression strength of building block is lower than or approaching traditional thermal conductivity Schwellenwert, and ultimate compression strength increases substantially, and the lagging material that adopts is a rice husk; Can reduce material cost, alleviate environmental protection pressure.
