Determination of water absorption of aggregate concrete Concrete Testing gravity solids content detection

Patent Number: ZL201320080171.0 three-year warranty effect: Confirm aggregate concrete gravity and water absorption ratio of the volume of data to achieve concrete effect and yet the economy. Function: simple, fast read a bulk density aggregate thickness of 2, water absorption, apparent porosity, wet density and volume specifications: ASTM C39, ASTM C128, ASTM C127, AASHTOT 84, GB / T23561 standards Step 1 the sample is placed in the measurement stage, press the M key. Step 2, the vacuum saturated water, on the measuring table, press the M key. Step 3, after the samples were saturated water into the water spider, press the M key. Step 4, direct display density, water absorption, effective porosity, wet density, volume models TWD-150N test types: solid, granular body, float Maximum weighing: 150g Weighing Accuracy: 0.001g density accuracy: 0.0001 g / cm3 density range:> 1 <1 Jieke tests showed values: density, volume, porosity temperature, solution set of compensation: 19.999 solution compensation can be set online interface: RS-232 Advantages: 1, the body of aluminum alloy casting, structural stability. It does not exist because of keystrokes and the impact sensing element to detect, causing instability screen appears. 2, the body is integrally formed, because there is no solution overflow penetrate the circuit board and sensor damage caused problems. 3, the machine's sensors measure the position and the same platform, because there is no corner of the load factors, resulting Deviation measurements. 4, the screen mining elevated independent design and measurement station separation, the panel due to infiltration and adhesions solution, and there is no question of damage. 5, the equipment weight to volume expansion, solution expansion and air buoyancy compensation.
