Standard test methods for density of soil and rock in place by the sand replacement method in a test pit 用试验井中砂子替代法在现场对土壤和岩石的密度的标准试验方法
Take their paw and gently move it in a digging motion to help them see what they can do with this litter 你抓着他们的爪子，轻轻的在砂子里面挖挖，帮助它们了解到如何使用猫砂。
It also provides a measure of safety in that no objects ( gravel , for example ) are so easily blown into the street below 它同时提供一种防止物品（例如砂子）轻易地被风吹到下面街道的安全措施。
After heated at the temperature of 400 - 800 , the cement mortar became the dehydrated phases of cement hydrates and sand 经400 - 800热处理后，水泥砂浆形成水泥水化产物的脱水相和砂子的混合物。
When they begin to go to the bathroom elsewhere , just move them to the litter pan and repeat the scratching motion with their paw 当它们开始到处便便的时候，只要把它们弄到猫砂盒里，抓着它们的爪子重复挖砂子就可以了。
Tests relating to pavements . freezing behaviour of materials treated with hydraulic binders . part 1 : freezing - thawing test of stabilized gravel or sand 路面试验.经水硬性粘结剂处理的材料冻结性能.第1部分:粗砂和经处理的砂子的抗冻结和解冻试验
Recycling circulating times of sand in the machine can be regulated to gain the recycling sand in line with different demands and states of the used sand 根据工艺不同要求和旧砂不同情况，可调整砂子在该机中的再生循环次数，达到满足工艺要求的再生砂。
Special roller type structure of this product it has won national patent , cn94220134 5 has fast heating speed , no pollution on sand and lower repairing times 本产品独特的滚筒式结构设计已获国家专利， cn94220134 ， 5使之加热速度快，对砂子的污染，使用可靠维修量很小。
With small amount of chemical additive , this cementious system and sand of rejected cement mortar can be directly got dry - mixed mortar met the application requirements 在少量化学和矿物助剂的作用下，利用该胶凝材料体系和原砂浆中的砂子可直接制成满足使用要求的建筑干混砂浆。
