砂浆密度仪依据行业标准JGJ70-90《建筑砂浆基本性能试验方法》而设计的专用仪器。砂浆密度仪适用于测定砂浆拌合物捣实后的单位体积质量（即密度）。以确定没平方米砂浆拌合物中各组成材料的实际用量。

Mortar density meter is a special instrument designed according to the industry standard JGJ70-90 "Basic Performance Test Method for Construction Mortar". Mortar density meter is suitable for measuring the mass per unit volume (that is, density) after tamping the mortar mix. Determine the actual amount of each component in the square meter mortar mix.

砂浆密度仪结构参数：

★量筒内径：108mm

★净   高：109mm

★筒壁厚：2mm

★容   积：1L

Structural parameters of mortar density meter

★ Inner diameter of measuring cylinder: 108mm

★ Clear height: 109mm

★ Cylinder wall thickness: 2mm

★ Capacity: 1L

试验步骤：

★试验前秤出容量筒重，**至5g，然后将容量筒的漏斗套上，将砂浆拌和物装满容量筒并略有富余。根据稠度试验方法分别用插捣法或震动法，添加砂浆至装满。

★将筒口多余砂浆拌和物刮去，使表面平整，然后将容量筒外壁擦净，秤出砂浆与容量筒总重，**至5g。

Test steps of mortar density meter:

★ Before the test, weigh out the capacity cylinder, ** to 5g, then cover the funnel of the capacity cylinder, and fill the mortar with the mortar mixture with a little margin. According to the consistency test method, the mortar or the vibration method is used to add mortar to full.

★ Scrape the excess mortar mixture at the mouth of the cylinder to make the surface smooth, then wipe the outer wall of the volumetric cylinder, and weigh out the total weight of the mortar and the volumetric cylinder, ** to 5g.
