Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 208-1994 "cement density determination." This standard compared with GB/T 208-1994 main changes are as follows. --- Liquid medium added "other liquid does not react with the cement reaction" (1994 edition, Chapter 4, Chapter 4 edition); --- Increased requirements for heated water tank, "thermostatic water bath should be large enough volume so that the water temperature can be stably controlled at 20 ℃ ± 1 ℃ "(1994 Version 5.3, this version of Article 5.3); --- Bubble discharge mode adds, "You can use a magnetic stirrer discharge bubble" (1994 version 6.4, this version 6.4). The standard proposed by China Building Materials Federation. This standard by the National Standardization Committee cement (SAC/TC184) centralized. This standard is drafted by. China Building Materials Academy, Urban Construction Zhejiang Construction Group Co., Ltd., Xiamen Yi Siou standard Sand Co., Ltd., Beijing's new Austrian concrete Group Limited. Participated in the drafting of this standard. Xinjiang Tianshan Cement Co., Ltd., Shandong jungle Group Co., Ltd., Jiaxing day extension supplies Limited, Mudanjiang Northern Cement Co., Ltd., Qufu United Cement Co., Ltd.

This standard replaces the standards previously issued as follows. --- GB 208-1963, GB/T 208-1994. Cement density determination

1 Scope

This standard specifies the method for determining the density of the principle of cement, machinery and materials, measurement step and results calculation. This standard applies to the determination of the density of the cement, but also to specify other measuring density of powder material using this method.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For undated references, the latest edition (including any amendments) applies to this document. GB 253 Kerosene

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Cement density cementdensity Cement mass per unit volume.

4 principle of the method

Bottle, the volume of liquid will be Lee certain quality of cement was poured into a liquid medium containing a sufficient amount should be able to fully wet cement particles. According to Archimedes' principle, the volume of cement particles is equal to the volume of fluid it displaces, to calculate a quality of cement per unit volume is dense degree. Test, the liquid medium using anhydrous kerosene or other liquid does not react with cement.

5 Apparatus and materials

5.1 Lee bottles Lee bottles made from high quality glass, transparent without stripes, with resistance to chemical attack and thermal hysteresis is small, there must be sufficient thickness to ensure good Good crack resistance. Lee bottles circular cross-sectional shape, dimensions shown in Figure 1. Bottleneck scale by the 0mL ~ 1mL and 18mL ~ 24mL two scale composition and 0mL ~ 1mL to 18mL ~ 24mL and 0.1mL of dividing the value of any error no larger than the capacity indicated 0.05mL.
