Penetrated cement concrete penetration coefficient testing apparatus and method thereof

Abstract

The invention relates to the technical field of engineering material test, and especially relates to a penetrated cement concrete penetration coefficient testing apparatus and a method thereof. The apparatus comprises a cylinder having a constant up and down wall thickness, a three-plate die connected to the lower end of the cylinder in a seal fixed manner and having a consistent internal diameter with the cylinder, and an overflow water tank, the three-plate die is cylindrical in shape and is formed by merging three die plates, a hoop is sleeved outside the three die plates, a circular ring platform is arranged at the central portion of the inner ring of the three-plate die, circular holes are uniformly distributed at a same height of the lower portion of the three-plate die, an overflow water tank overflow port is arranged at the upper portion of the overflow water tank, a cylinder overflow port is arranged at the upper portion of the cylinder, and the cylinder overflow port is connected to a position outside the overflow water tank through a pipeline. Te apparatus and the method have the advantages of test of the penetrated cement concrete penetration coefficient, guarantee of the side surface sealing performance by the rubber gaskets between the cylinder and the three-plate die, improvement of the penetration coefficient measuring precision, and convenient and fast mounting and dismounting.

Description

technical field [0001] The invention relates to the technical field of civil material testing, in particular to a testing device and method for permeability coefficient of permeable cement concrete. Background technique [0002] With the development of urban construction, modern urban roads are gradually covered by impermeable concrete. While convenient transportation facilities bring convenience to people, at the same time, due to the lack of water permeability and air permeability of impermeable road surfaces, certain negative effects such as "heat conduction effect" are brought about. ", the rainwater cannot return to the ground in time to cause the ground to sink, and the road area will reduce the safety and comfort of traffic during heavy rain. [0003] Permeable concrete, also known as porous concrete and permeable floor, is a porous lightweight concrete made by mixing aggregate, cement and water. It does not contain fine aggregate and is covered with a thin layer of c...
