Problems solved by technology

With the diversification of the construction environment, the related technologies are also continuously in-depth research in subdivided fields. At present, the research on high fluidity concrete and fresh concrete has gradually deepened, and there is no research on the flow properties of emerging materials in China. Therefore, we propose a concrete rheometer

Abstract

The invention discloses a concrete rheometer. A charging barrel is mounted on one side of the top of a base through a protection seat; a stand column guide rail is mounted on the other side of the topof the base through a screw rod; a water bath is arranged on one side of the base; a motor base is installed on one side of the stand column guide rail through a sliding rail. A servo motor is mounted at the top of the motor base through a connecting frame; one side of the servo motor is electrically connected with a voltage monitor through a wire; a driving end on one end of the servo motor is connected with a transmission end of a speed changing device through a mounting frame, a driving end of the bottom of the speed changing device is connected with a torque sensor, and a rotating end ofthe bottom of the torque sensor is connected with a stirring shaft. The concrete rheometer has the advantages that the design is reasonable and simple, the operation is convenient, the stability is good, the reliability is high, the safety is good, and the concrete rheometer is suitable for wide popularization.

Description

technical field [0001] The invention relates to a rheometer, in particular to a concrete rheometer. Background technique [0002] As early as 1923, D.A. Abrams of the United States proposed the slump test, which can be regarded as the fluidity of cement concrete under its own gravity under the condition of zero shear rate, and the slump test standard is a static test , is not a measure of workability. The slump test has certain limitations, and it is not suitable for this test method for mixtures or other media with high fluidity. With the diversification of the construction environment, the related technologies are also continuously in-depth research in subdivided fields. At present, the research on high fluidity concrete and fresh concrete has gradually deepened, and there is no research on the flow properties of emerging materials in China. Therefore, we propose a concrete rheometer. Contents of the invention [0003] The main purpose of the present invention is to pr...
