On the basis of theory analysis , we have set up the ideal mode of high toughness and strength lightweight aggregate concrete , which sets an important basis for the designation , preparation and produce of hslc , and we also set up the brittleness destruction model of high - strength lightweight aggregate according to many experimental data . the course of hslc ' s destruction includes four stages : elastic stage of line , strengthening stage , stage of falling of stress and soften stage 通过实验分析了高强轻集料混凝土脆性的影响因素：水胶比、砂率、胶凝材料组成和轻集料种类，以及它们与高强轻集料混凝土脆性之间的关系；在实验和理论分析的基础上，建立了高强轻集料混凝土的理想模型，为设计、制备和生产高强高韧性轻集料混凝土提供了理论依据。
The huaxing co . , ltd casts the limited company craft forerunner , the material is excellent , the technique power is strong , the ball mo iron casting piece produce has the high tenacity of strength good , bear the high pressure and bear the corrosive good characteristic , is the iron piping a most ideal renewal of traditional ash to change a product , is welcome by domestic and international customer deeply 华星铸造有限公司工艺先进、装备精良、技术力量雄厚，所产球墨铸铁件具有强度高韧性好、耐高压、耐腐蚀的优良特性，是传统灰铁管件最理想的更新换代产品，深受国内外用户欢迎。
The results revealed that the essential condition occurring brittle - tough transition in such ternary system was l ? lc ( ? 0 . 095 ? m ) , and the effect of above factors on the impact behavior followed percolation mechanism which indicated that it was some reasonable using lc as single parameter criterion of brittle - tough transition of pp / eoc / caco3 composites . the micro - deformation model at different dispersing morphology was then proposed 首次将聚合物复合材料脆韧转变机理的定量化研究从二元体系拓宽到三元体系，对ppffioc aco3体系的配方进行设计，制备得到高刚性高韧性低成本的聚丙烯复合材料， eoc和cvco3的体积份数之和为25v （其中弹性体相为10v 。
However it was discovered after analyzing the properties measurement results obtained in the production of high toughness adi that , with increasing of their tensile strength from 908mpa to 1054mpa , the elongation , impact toughness , yield strength and hardness of alloyed high toughness adi castings did not change such obviously as for the normal non - alloyed adi castings 对高韧性等淬球铁铸件的生产检测结果进行了分析，发现合金化的高韧性等淬球铁铸件的力学性能之间的关系与一般非合金化等淬球铁铸件不同，其伸长率、冲击韧度、屈服强度、硬度在一定范围内随抗拉强度的提高改变不大。
When it is used to take the place of asbestos to make cement products , the ultra short staple plays an important role in improving the quality of cement products which have stronger resistance to shock and better toughness because the staple has strong resistance to acid and alkali and also it has good dispersing ability in the cement mortar 因其耐酸碱性强在水泥浆中分散性能好，用于替代石棉制水泥制品时，其制品抗冲击强度高韧性好，可提高制品的档次和质量。
