Abstract

The invention discloses a testing device and method for rapidly predicting the masonry mortar strength through a formwork coagulation steam curing method. The testing method comprises the following steps: 1, a mortar test block with the dimension being 40 mm*40 mm*50 mm is subjected to formwork coagulation steam curing for 3.5 h and 4.5 h; 2, the standard compression strength values f<3.5 h> and f<4.5 h> of the mortar test block in the step 1 are obtained through an axial compression test; 3, an appropriate prejudging formula is selected; and 4, f<3.5 h> and f<4.5 h> in the step 2 are substituted into the corresponding prejudging formula to obtain the prejudging strength value f<28 d> of the mortar test block 28 d under the standard curing condition. During actual engineering detection (4.5 h), the testing device and method can prejudge the masonry mortar strength more quickly, and better serve engineering construction.

Description

technical field [0001] The invention relates to the fields of masonry engineering and mortar, and provides a test device and method for quickly predicting the strength of masonry mortar by a steam curing method with mold coagulation acceleration. Background technique [0002] In actual engineering, construction companies often encounter the problem of engineering economic losses due to the inability to predict the quality of mortar in time. If the strength of mortar can be quickly predicted and used to guide engineering construction, it can be avoided or reduced to a certain extent. The occurrence of similar problems reduces unnecessary losses. [0003] At present, the related work of mortar strength prediction is seldom carried out, and the prediction time is also long. It is impossible to know the mortar ratio and the development of mortar strength in time, which will affect the progress of the project and cause unnecessary economic losses.
