Description
Technical Field
The utility model belongs to the technical field of concrete void fraction testing arrangement, concretely relates to simple and easy porous concrete porosity detection device.
Background
There are three types of pores in porous concrete: the first is a closed pore; the second is open but discontinuous pores, which we call "cloth bag type" pores, the presence of which is too much to be detrimental to the water permeability of the porous concrete; the third is continuous pores through the concrete, which play a crucial role in the water permeability of pervious concrete, and are the main factor for its water permeability.
The first method is to fully soak a block to be tested in water, take out the test block, air-dry the test block until the surface is moist but no water exists, and then immerse the test block in a container to measure the volume difference of the container. However, the premise of the accuracy of the test method is that the pores of the test block are filled with sufficient moisture and are easy to volatilize. However, some closed holes and cloth bag type holes in the test block are difficult to fill with water, so that the measurement data is small; the second method is drainage porosity. And (3) measuring the mass of the test block in the air, boiling the test block in boiling water for 5 minutes to fully discharge the gas in the test block, and then measuring the mass of the test block in the water to calculate the porosity of the test block. The method is used for measuring the connected porosity of the test block, the porosity of the test block is measured through mass, so that the precision is higher than the porosity measured through volume, the numerical value is slightly higher than the porosity measured through volume, and a corresponding testing device is needed for conveniently testing.
