灰砂砖

Background: The main raw materials of lime sand bricks are tailings of silicon materials and calcium lime. They are standard bricks made through mixing, pressing and autoclaving. Their features include beautiful appearance, good quality and high solidness. An ideal substitute for clay bricks, they can be widely used in the base, the interior and exterior walls of constructions.

一、项目背景：灰砂砖是以硅质材料尾砂和钙质材料石灰为主要原料，经混和、压制、蒸压工艺制成的标砖，具有外观质量好、强度高等性能，可广泛应用于建筑物基层，底层及内、外墙体，是理想的实心粘土砖的替代产品。

Jinta County Sand Building Materials Industry Co., Ltd. The annual production capacity of sand-lime brick 10,000 over 1500, the production of gas 10,000 cubic meters block.

金塔县砂业建材有限公司年生产灰砂砖能力达1500多万块，生产加气块1万立方米。

Yu Sheng About the Company predecessor Yu Sheng Machinery Plant was set up in 1993, changed its name to convert 99-Yu Sheng Machinery Co., Ltd., over the years to lifting equipment, chemical equipment, sand-lime brick production line mainly associated equipment .

本公司前身禺生机械厂于一九九三年成立，九九年转制改名为禺生机械设备有限公司，多年来以起重设备、化工设备、灰砂砖生产线配套设备为主。

Over the years, the company to new wall-based equipment, the new wall materials and equipment modernization as a strategic positioning, develop and produce various types of Press Products: automatic hydraulic press,×ú, fly ash sand brick, autoclaved sand-lime brick.

多年来，公司以新型墙材设备为基点，把新型墙材装备现代化作为战略定位，研制并生产出多种类型的压砖机产品：全自动液压砖机，免烧砖机，粉煤灰砂砖机，蒸压灰砂砖机。

To reveal the complicated stress state of masonry structure in project and the effect of normal stress on shearing behavior,failure form and shearing strength,the shearing strength was obtained through experiments on 54 pieces of minitype sand-lime autoclaved aerated concrete masonry subjected to different normal stress.

为了解砌体结构在实际工程中所处的剪压复合的复杂受力状态，作用在砌体上的正应力对砌体的抗剪性能、砌体的剪切破坏形态及其对砌体抗剪强度的影响，对54个小型灰砂蒸压加气混凝土砌体进行静力抗剪试验，通过施加不同的正应力得到相应的抗剪强度；分析其破坏机理，归纳得出剪摩、剪压、斜压等破坏形态，并与砖砌体的破坏形态进行比较；根据试验结果回归分析得到灰砂蒸压加气混凝土砌体的静力剪压相关性曲线，与砖砌体的剪压相关性曲线进行对比分析，得到两者的异同；在静力剪压相关性曲线的基础上，依据变摩擦系数的剪摩理论，提出灰砂蒸压加气混凝土砌体静力抗剪强度的建议公式，并对摩擦系数进行了简化
