In order to meet the design requirements and solve the problem of the combination of layer height and block height, this enterprise combines the characteristics of different requirements for different parts of the infill wall block currently used in the frame construction, in order to increase the hole rate and increase the thermal resistance. Improve the insulation effect, using the form of groove, square hole, half back, double row hole. The specifications of small hollow blocks are: 390 × 190 × 190mm, 290 × 190 × 190mm, 190 × 190 × 190mm, double row holes: 390 × 190 × 190mm, 190 × 90 × 190mm, 90 × 190 × 190mm; Row hole: 190×90×65mm, used for fixing windows and doors and windows, and 190×190×190mm, 390×190×190mm, U-shaped blocks, etc.
In recent years, with the continuous in-depth development of wall materials innovation, small hollow blocks have emerged in spring and spring to become the leading product of non-bearing wall materials. At present, most of the raw materials used by many companies are dominated by coal slag, which leads to rising raw materials. The shortage of coal slag is outstanding, and some companies have reduced the cost and caused poor product quality. In view of this situation, Liaohe Chemical Plant in Liaozhong County, Liaoning Province developed a 0.3 to 0.8 cm crushed stone waste material for the quarrying plant as a coarse aggregate, a bottom aggregate ash for the power plant as a fine aggregate, and a common cement as a cementing material to produce a new type hollow core. Blocks. In addition to its excellent performance, the cost of the product is about 20% lower than that of a cinder hollow block, and it has good economic, social and environmental benefits.
