1) strength of molding sand
型砂强度
2) strength and toughness of the molding sand
型砂强度和韧度
1.
skimming of the molten iron during pouring; (3 )poor anti-washing resistance of the mold surface; (4)using stripping agent not correctly; (5) manually digging out gating system; (6) strength and toughness of the molding sand not enough.
湿砂型铸铁件产生砂孔和渣孔缺陷的主要原因是:(1)芯头或砂台的间隙偏小;(2)浇注时铁液清渣不良;(3)砂型表面耐铁液冲刷性能较差;(4)脱模剂使用不当;(5)手工开挖浇注系统;(6)型砂强度和韧度欠佳。
3) sand strength testing machine
型砂强度试验机
4) cement mortar strength
胶砂强度
1.
At the equal w/c ratio,the fluidity and the cement mortar strength of the coarser separated fly ash were low.
在相同水胶比的条件下,掺分选粗粉煤灰的水泥胶砂流动度及强度均低;分选粗粉煤灰磨细后,不仅减少了颗粒的粘连,增加了比表面积,而且提高了粉煤灰的反应活性和水泥胶砂流动度及强度,虽其水泥胶砂流动度仍小于掺分选细粉煤灰的水泥,3d水泥胶砂强度也略低,但其28d水泥胶砂强度略高于掺分选细粉煤灰的水泥;在相同水泥胶砂流动度的条件下,掺磨细粉煤灰配制的水泥胶砂3d强度低于掺分选细粉煤灰的水泥,但随着水化龄期的增长,其差距逐步缩小,至60d时可超过后者。
5) Mortar strength
胶砂强度
1.
Influence of fly ash and phosphorus slag on hydration heat and mortar strength of cement
粉煤灰与磷矿渣对水泥水化热及胶砂强度的影响
2.
Effect of alcohol amine admixture on hydration of Portland cement and mortar strength
醇胺类助磨剂对硅酸盐水泥水化及胶砂强度影响的研究
3.
In this paper,the variety of cement-Mortar strength was measured after adding mineral admixtures by experiment,and the effect of mineral admixtures on developing regulation of cement-Mortar strength was investigated.
本文通过试验检测掺加矿物掺合料后水泥胶砂强度的变化,研究矿物掺合料对水泥胶砂强度发展规律的影响。
