结论对于混凝土冬季施工更合适未用自然变低温养护的方法，掺入适量的掺合料能使混凝土孔隙率显著降低，使混凝土更加密实，提高混凝土的抗冻性。 |
| 7. | This paper analyzes the factors affecting the controlling precision of sand compactibility system and sets up the dynamic model of regression coefficient between sand compactibility and water content . to prevent the insufficiency or excess of sand water content , the amount of the first addition is set as 80 % of the total water addition amount . after the first water addition , we adopt ar model to predict the stable value of sand compactibility to shorten the time mixing the sand . each time we add water , the correction coefficient is introduced to adapt to the change in the composition of sand . the experiment shows that the mathematics model not only makes the water content in sand reach the best range within shorter time , but also directs how the sand composition should be adjusted , which can better conform to the actual situation
分析了影响型砂紧实率控制精度的因素，建立了型砂紧实率-水分回归系数的动态模型.为防止型砂水分不足或过量，将第一次加水量设定为总加水量的80 .第一次加水后，对型砂紧实率稳定值采用ar模型进行预测，以缩短型砂混制时间.每次加水后，引入修正系数，以适应型砂组成的变化.实验表明，该数学模型不仅使型砂水分含量在较短时间内达到最佳范围，同时可指示对型砂组成进行调整，能较好地符合实际情况 |
| 8. | The result shows that the compressive strength of concrete under natural variational low temperatural curing is higher than the compressive strength of concrete under permanent low temperatural curing and the pore porosity under natural variational low temperatural curing is less than the compressive strength of concrete under permanent low temperatural curing ; the compactibility of concrete is good with fa ( < 15 % ) and sf ( < 8 % )
结果当掺合料掺量相同时，自然变低温( - 15 ~ 5 )养护条件下混凝土抗压强度高于恒低温( - 10 )养护条件下混凝土抗压强度，孔隙率要低于恒低温( - 10 )养护条件下混凝土的孔隙率;当单掺粉煤灰时掺量低于15 % 、单掺硅灰时掺量低于8 % ，低温混凝土的密实性较好。 |
