| description | The invention provides a mortar crack resistance evaluation method and detection device, and the method comprises the following steps: pouring stirred mortar into a mold, and standing for a first preset time to obtain a test piece; demolding the test piece, controlling the test piece to evaporate moisture at a preset rate, and starting timing; when timing reaches second preset time, the number of cracks on the test piece and the width corresponding to the cracks are detected and recorded, all the cracks are classified according to the widths of the cracks and preset crack categories, each crack category is correspondingly provided with a weight value, the sum of products of the widths of all the cracks and the corresponding weight values is calculated, and the sum of products of all the cracks and the corresponding weight values is calculated; the cracking index of the test piece is obtained. According to the method, the anti-cracking performance of the corresponding mortar can be quantitatively analyzed thro |
