砺灰是利用沿海储量丰富的海生贝类残骸烧制而成的一种黏结材料，类似于当代的水泥；我国有利用砺灰作为胶凝材料的大量古工程，砺灰是我国古代科技成就的一个重要组成部分。砺灰力学特性试验研究了标准砂、糯米粉、黄泥的掺量对砺灰砂浆抗折及抗压强度的影响，研究结果表明细集料对砺灰砂浆抗折及抗压强度影响较大，用于配制砺灰砂浆的细集料必须具备一定的强度。

Li ash is the use of abundant coastal Marine shellfish debris burn becoming a bonding material,similar to the modern cement.Our country use Li ash as a large number of ancient engineering of cementitious materials.Meanwhile,Li ash is an important part of scientific and technological achievements in ancient China.Li ash experiment studies the influence of the mechanical properties of standard sand, glutinous rice powder,yellow dosage and compressive strength.It shows that fine aggregate has a great effect on the flexure of grind mortar and compressive strength and it must have certain strength to make issue of ash mortar fine aggregate.
