In order to develop a High Performance Cementitious Composites (HPCC), material design criteria were studied. For possessing light weight, high strength and high toughness, micromechanics approach was introduced. Mix proportion of matrix was discussed on the basis of packing theory and various types of fibers were experimentally studied Effect of processing was also investigated.The following results were obtained.(1) Packing theory works well to find a suitable mix proportion to produce a dense matrix to achieve high strength matrix(2) Not only the performance of matrix and fiber, but also the suitable combination of these two components are very important to produce HPCC.(3) Exclude processing is very useful to produce HPCC.(4) Experimental results were analyzed by a multi regression analysis to formulate design criteria for five performance indexes that are the maximum flexural strength, deformability, and three toughness indexes.

为了开发高性能胶结复合材料（HPCC），研究了材料设计标准。为了具有轻巧的重量，高强度和高韧性，引入了微力学方法。讨论了基质的混合比例，根据包装理论进行了讨论，并且还研究了各种类型的纤维。还研究了处理的处理效果。（1）填料理论非常有效地找到合适的混合比例来产生密集的矩阵以实现高强度矩阵（2）不仅是矩阵和纤维的表现，而且还适合这些矩阵和纤维的表现，这是两种组合的组合，这是两个组合的组合。 （4）通过多回归分析分析实验结果非常有用，以制定五个性能指数的设计标准，这些绩效指数是最大弯曲强度，变形性和三个韧性指数。
