Underwater-non-dispersion neat paste material dispersion resistance comprehensive tester and application thereof

Abstract

The invention discloses an underwater-non-dispersion neat paste material dispersion resistance comprehensive tester and application thereof, and belongs to the technical field of neat paste material dispersion resistance testing instruments. The comprehensive tester comprises a main support, a first branch support and a second branch support are fixedly connected to the main support; a quality testing device is arranged on the first branch support and is connected to an automatic lifting device; the automatic lifting device is connected with the neat paste container through a connecting rope; a pH testing device is arranged on the branch bracket II; a water container is arranged below the pH testing device; and the quality testing device, the pH testing device and the automatic lifting device are electrically connected with the computer processing end. According to the tester provided by the invention, a weighing method and a pH method are combined to represent the dispersion resistance of the underwater-non-dispersion neat paste material, a test basis and a test method are provided for the dispersion resistance of the underwater non-dispersion neat paste material, and the requirements of automatically, accurately and intelligently testing the dispersion resistance of the underwater-non-dispersion neat paste material can be met.

Description

technical field [0001] The invention relates to the technical field of testing instruments for the anti-dispersion performance of clean pulp materials, in particular to a comprehensive test instrument for the anti-dispersion performance of underwater non-dispersible clean pulp materials and its application. Background technique [0002] Concrete is a hydraulic material, but due to the low cohesion between the components in fresh concrete, it will immediately disperse underwater when it is directly poured into water. In order to solve the problem of fresh concrete dispersing when it encounters water and improve the quality of concrete underwater construction, it is usually used to add an appropriate amount of underwater non-dispersing agent to improve the bonding ability of concrete, thereby improving the anti-dispersion performance of concrete, so that it can achieve water Under pouring terrestrialization. The invention and history of underwater non-dispersible concrete has...

Problems solved by technology

However, due to the unevenness of underwater non-dispersant products in the domestic market, the anti-dispersion performance in practical applications varies greatly. The main reason is that the anti-dispersion mechanism of different underwater non-dispersants acting on concrete has not yet been clarified.

In order to better study its performance mechanism, considering the complexity of the concrete solid-liquid-gas system, the research should generally start with the clean slurry material. However, the current relevant regulations only stipulate the installation method for underwater non-dispersible concrete, which obviously cannot be directly applied to water. Anti-dispersion performance test of non-dispersible pulp materials

In addition, at present, industry personnel only focus on how to conduct relevant tests on the performance of underwater non-dispersible concrete, but there is no relevant test method for the application of underwater non-dispersible grout materials, and it is only judged by visually observing its underwater pouring
