Description

Concrete slump measuring tool

Technical Field

The utility model relates to the technical field of concrete testing, in particular to a concrete slump measuring tool.

Background

Slump mainly refers to plasticizing performance and pumpability of concrete, and is used for judging whether construction can be normally performed or not by measuring the degree (plasticizing performance and pumpability) of the concrete by using a quantitative index. The concrete slump is mainly affected by graded change, water content, weighing deviation of a flat knitting machine, and the dosage of the additive is easily ignored and the temperature of cement is also changed. Slump refers to the workability of concrete, specifically, to ensure the normal progress of construction, including water retention, fluidity and cohesiveness of concrete. Workability means that the concrete mixture is easy to construct and operate (mixing, transporting, pouring, tamping) and can obtain the concrete performance with uniform and compact quality. Workability is a comprehensive technical property including the definition of water retention, flowability and cohesiveness. The workability is influenced mainly by water consumption, water-cement ratio, sand ratio, cement variety, aggregate condition, time and temperature, additive and the like;

the existing concrete slump measuring device only fills concrete through the slump cylinder, then lifts the slump cylinder, and measures the front and back concrete height.
