Study on the Factors Affecting the Accuracy of the Unit Water Consumption Test
摘要
Abstract
It′s hard to avoid the errors during the process of the unit water consumption test, and the effect of these errors to the results of the test is unknown. This article analyzed the influence on unit water consumption separately from many a single-factor or combination factors as the precision of the weighing instrument, air content, material density, temperature, etc. Theresultsshow that theabove factors all have dif-ferent impacts on the test, of which, the combination factor of air content and the balance has the biggest impact on unit water consumption, while the temperature's influence is minimal. The results have a guiding significance for the determination of water cement ratio.关键词
