摘　　要：通过对混凝土普通砖砌体受压试验结果的对比和分析,讨论了混凝土普通砖砌体在竖向压力作用下裂缝的发展特点和变形规律;得出了混凝土普通砖砌体弹性模量、泊松比计算公式。结果表明,混凝土普通砖砌体弹性模量随着砂浆强度等级的提高而提高。并与粘土砖砌体的弹性模量公式进行对比分析,得知弹性模量的试验值是收敛的、可靠的,作为承重的新型墙体材料,混凝土普通砖砌体有较好的抵御变形的能力。Based on the experimental result and analysis of the concrete solid brick masonry members under compression,the developing feature of cracks and transfiguration law of concrete solid brick masonry are discussed in detail.The formula calculating the elastic modulus of concrete solid brick masonry member is given.It is obvious that the elastic modulus of concrete solid brick rises with an increase of the mortar strength.The paper comes to the conclusion that the test value of elastic modulus is convergent and reliable.These bricks have better resistance of deformation.As a result,they can be used as bearing new wall material.
