RESEARCH FOR MEASUREMENT ON LINE AND AUTOMATIC COMPENSATION OF MOISTURE COTENT OF SAND |
| |
| Abstract: | The use of measurement on line and automatic compensation technique for moisture content ofsand is introduced in this paper. By the techniques, the quantites of sand and water in mixing con-crete can be regulated in time, and then the accuracy of batching is proved according to the givenmixing ratio. Therefore, the quality of concrete is improved and the quantity of cement is reduced. |
