摘要： The weight of aggregate for preparing concrete and mortar is measured while the aggregate is immersed in water contained in a container. The water in the container is discharged and the water in the interstice in the aggregate is also removed. Thereafter the weight of the aggregate is measured again. These measured values of the aggregate are used to determine the quantity of water to be added to the aggregate when it is used to prepare concrete or mortar.

摘要： In the preparation of a cement paste about 30 to 76% of the total water is added to the cement to form a funicular state, capillary state or slurry state, and the resulting mixture is kneaded so as to reduce the coagulated lumps of cement. Then the remaining quantity of water is added and the composition or mixture is kneaded again. Sand and/or gravel may be incorporated after the firstly kneaded mixture. The resulting cement paste, mortar or green concrete exhibits a small percentage of bleeding water and products prepared therefrom have a high compression strength.

摘要： The fluidity of a plastic fluid, cement mortar for example, is measured by passing the fluid through a flow passage packed with an aggregate for simulating an actual mould, measuring the flow pressure, and measuring the quantitative flow coefficient between the fluid and the flow passage. The pressure remaining in the passage after the fluid has been poured into the passage and after the flow speed has been decreased to zero or the pressure after a quantity of the fluid has been added to the passage and prior to the discharge of the fluid from the passage is measured to determine the relative shear stress yielding value. Thereafter, the fluid is caused to flow to determine again the relative shear stress yielding value, and the relative closure coefficient is determined by the difference between said two relative shear stress yielding values. After the elapse of a predetermined time the plastic fluid is caused to flow under a pressure and the pressure at the commencement of the flow is measured to quantitatively determine the variation in the shear stress yielding value with time, thereby determining the relative initial flow pressure. The relative flow viscosity coefficient is measured by varying the flow speed of the plastic fluid and by determining the relationship between the speed and the pressure of the plastic fluid. In the actual moulding operation the plastic fluid is prepared by using the factors thus determined and the pouring conditions are predetermined, or automatically controlled.
摘要翻译：塑料流体，例如水泥砂浆的流动性是通过使流体通过填充有聚集体的流动通道来模拟实际模具，测量流动压力和测量流体与流动通道之间的定量流量系数来测量的。在流体已经被注入通道之后并且在流速已经降低到零之后剩余的通道中的压力或在一定量的流体被添加到通道之后并且在从流体排出流体之前的压力测量通道以确定相对剪切应力屈服值。此后，使流体流动以再次确定相对剪切应力屈服值，并且相对闭合系数由所述两个相对剪切应力屈服值之间的差确定。在经过预定时间之后，使塑料流体在压力下流动，并测量流动开始时的压力，以定量地确定剪切应力屈服值随时间的变化，从而确定相对初始流动压力。通过改变塑料流体的流速并通过确定塑料流体的速度和压力之间的关系来测量相对流动粘度系数。在实际的模制操作中，通过使用如此确定的因素和倾倒条件被预先确定或自动控制来制备塑料流体。
