Abstract
The small hollow block of light aggregate concrete has surface layer comprising cement, ore powder, and early strengthening agent in the weight ratio of 1 to 3 to 0-0.0012; and middle layer comprising cement, ore powder, foamed plastic block and early strengthening agent in the weight ratio of 50 to 10 to 1-1.2 to 0-0.05 as well as mortar glue. The production process of the small hollow block of light aggregate concrete includes spreading ore powder slurry for the first surface layer in 15-20 mm thickness, setting one parallel core over the surface layer; spreading ore powder slurry for the middle layer in 80-160 mm thickness, and spreading the second surface layer in 15-20 mm thickness. The product is light and high in heat maintaining performance.
Description
Technical field the present invention relates to constructional materials that a kind of constructional materials, particularly interior wall use and preparation method thereof.
Background technology is along with the development of construction business; people have invented some new constructional materialss again, and as disclose its main contents of a kind of (Light trabs and preparation method thereof) (application number 91108526.2) on the Gazette of Patent for Invention on April 1st, 1992 be: Light trabs is made of topping, glass layer and intermediate layer.Other material weight proportioning that constitutes wallboard is: cement 20-25%, perlite 20-25%, gypsum 2-3%, alumina 2-3%, refractory material 5-8%, water 30-35%, earlier lysed gypsum of cement, perlite, refractory material and water and alumina are put into mixer by weight ratio during making, once add and be poured into mould after water stirs, and the moulding of vibrating, its weak point is that matter is heavy, heat-insulating property is not good enough, and hardening time is long, and occupied ground is big.
Summary of the invention the object of the present invention is to provide a kind of, high insulating effect low from heavy and light, cost, hardening time is short, occupied ground is few Lightweight aggregate concrete small hollow block and preparation method thereof.The used primary raw material of the present invention has: cement, breeze, foam-plastic blocks, mortar special glue and early strength admixture.Wherein cement is 500
#Above portland cement; Breeze is to pulverize through mill, and can cross the bluestone powder and the granule of 5 * 5mm grid; Foam-plastic blocks is the rigid foam particle that specification approximates the soya bean size; The mortar special glue is the cementing agent of bonding cement and foamed plastics, and early strength admixture (or claiming waterproof agent) is the additive that acceleration cement and other raw material are solidified togather.
The structure of product of the present invention is: the intermediate layer that accompanies light hollow between two panels.Therefore panel is different with the composition in intermediate layer.Wherein the used raw material of panel has: cement, breeze, water and early strength admixture.Following part by weight relation is arranged: cement: breeze: water=1: 3: an amount of between them.The mixture solidified time of above-mentioned raw materials shortens if desired, can in raw material, add early strength admixture, itself and cement have following part by weight relation: cement: early strength admixture=1000: 0-1.2, the used raw material in intermediate layer has: cement, breeze, foam-plastic blocks, mortar special glue, water and early strength admixture.Following part by weight relation is arranged: 1. cement between them: breeze: foam-plastic blocks: water=50: 10: 1-1.2: an amount of; 2. (cement+breeze+foam-plastic blocks): mortar special glue=500: 2-3; 3. cement: early strength admixture=1000: 0-1.2.
The preparation method of product of the present invention is as follows:
1. the making panel is modulated into breeze slurry for building with raw panels with mixer, and with its shop in one plane, thickness is the 15-20 millimeter then, preferably adopts the method for vibration to remove the bubble in the breeze slurry and make it density equalization everywhere.
2. making intermediate layer is provided with in parallel on above-mentioned panel and the fuse of certain interval is arranged with it.Lay intermediate layer breeze slurry on above-mentioned panel, its thickness is the 80-160 millimeter, and the bubble that preferably adopts method for oscillating to remove in the breeze slurry makes it density equalization everywhere.
3. make another panel, layer overlay thickness is the panel breeze slurry of 15-20 millimeter on above-mentioned intermediate layer.What obtain after above-mentioned each layer curing is light cement slab, and the product that obtains after cutting is the light aggregate concrete building-block.
The present invention has following advantage compared to existing technology:
1. the intensity of product and other index all are higher than standard GB 15229-2002, can increase usable floor area indirectly.
2. high insulating effect can be saved heat cost.
3. from heavy and light, can reduce the degree of depth of building foundation.
4. price is low, is lower than common brick and makes the light-weight hollow-brick price of raw material with sand, slag.
5. manufacture craft is simple, hardening time is fast, occupied ground is few.
Description of drawings
Fig. 1 is the schematic cross-section of product of the present invention.
The specific embodiment
Example 1 is with 100 kilogram 500
#Portland cement, 300 kilograms of breezes and an amount of water are added in the concrete mixer, stir and make it even mixing, and what obtain is that panel is starched with breeze.Have in the plane of template around this breeze slurry placed, vibration breeze slurry makes density equalization everywhere, and the breeze slurry that again thickness is surpassed 20mm is wiped off, and what obtain is this hollow brick panel 1.In parallel and the tubular core of certain interval arranged with it at above-mentioned panel.On above-mentioned panel, lay intermediate layer breeze slurry, this breeze slurry is earlier with 0.488 kilogram of stupid plate of smart board (after mortar special glue (the strong sunshine Concrete admixtures manufacturing company in Shenyang product) of EPS * PS) and water mixes, again with other raw material promptly 100 kilograms of 500# portland cements, 20 kilograms of breezes, 2 kilograms of rigid foam pieces be added to simultaneously in the concrete mixer, stirring, what obtain is intermediate layer breeze slurry.Vibration breeze slurry is removed bubble makes density equalization everywhere, and the breeze slurry that makes thickness surpass 150mm is wiped off, and what obtain is this building-block intermediate layer 2.On above-mentioned intermediate layer, repave last layer panel breeze slurry, will wipe off above the breeze slurry of 20mm after the vibration, obtain another panel 3 of this building-block.After above-mentioned each layer solidified, fuse was taken out in the demoulding, obtains light cement slab.Above-mentioned sheet material is cut into the fritter of 190*190*390, and the product that obtains is Lightweight aggregate concrete small hollow block as shown in Figure 1.
Example 2 repeats the operation of example 1, and wherein the raw material of panel breeze slurry also includes 0.12 kilogram of early strength admixture (building materials market product sold) it gives elder generation and mixes with the raw material water, is added in the mixer then.In the raw material of intermediate layer breeze slurry, foamed plastics is that 2.4 kilograms, mortar special glue are 0.734 kilogram.Also include 0.12 kilogram of early strength admixture in addition, together be added in the concrete mixer with water after it also needs to give elder generation and water mixes again, the upper and lower surfaces plate thickness is 15mm, and the thickness in intermediate layer is 80mm.
The said goods is through checking every technical indicator result as follows:
| Interventions Requested | Unit | Standard index | Assay |
