摘要
定义了粉煤灰胶凝系数β.β的影响因素主要为粉煤灰细度、需水量比和烧失量,并随龄期变化.可以细度、需水量比和烧失量这3个因素为自变量,建立函数关系确定β.需水量比对β的影响可由细度和烧失量来间接反映,因此可进一步简化,采用细度与烧失量的乘积来表征β.
The cementitious coefficient β is defined. Through analyzing, it is found that the main influencing factors of β are fineness, water requirement and loss of ignition. At the same time, β changes with the age of test specimen. Therefore β can be expressed as the function of the three factors: fineness, water requirement and loss of ignition. Among them, the influence of water requirement on β can be reflected indirectly by fineness and loss of ignition, so β can be expressed as the function with the product of fineness and loss of ignition as independent variables.
