The invention discloses a method for quickly detecting the strength of an autoclaved and aerated concrete block on site. The method comprises the following steps of: penetrating a detecting nail into the autoclaved and aerated concrete block to be detected by using 800N pressure, and converting the penetrating depth of the detecting nail into compressive strength y of the autoclaved and aerated concrete block by a strength detection curve; and calculating water content k of the autoclaved and aerated concrete block, wherein a conversion coefficient corresponding to the water content k is epsilon so as to calculate out reference compressive strength R of the autoclaved and aerated concrete block, i.e., R=epsilon*y. The method disclosed by the invention has the advantages that the autoclaved and aerated concrete block does not need to be taken back to a laboratory for the complex steps of sawing, drying, adjusting the water content and the like, so that the operation is simple, the detection result can be quickly obtained, the detection period can be shortened and the detection efficiency can be improved; and by adoption of the method, the strength of an autoclaved and aerated concrete block can be directly detected on site, and the product quality on the construction site can be guaranteed.
Description
technical field [0001] The invention relates to the field of performance detection of autoclaved aerated concrete blocks, in particular to a method and device for rapidly detecting the strength of autoclaved aerated concrete blocks on site. Background technique [0002] Autoclaved aerated concrete is a lightweight, multi-functional and environmentally friendly building material that has been used in my country and is still being vigorously developed. It has the characteristics of light weight, energy saving, heat preservation, fire prevention, heat insulation, waste utilization, and easy processing. In the wall enclosure structure of industrial and civil buildings. [0003] The quality control of autoclaved aerated concrete blocks is mainly through the inspection of the manufacturer and the entrustment of the construction unit, and the proportion of on-site supervision and random inspection is relatively small. According to GB / T 11969-2008 "Test Methods for Autoclaved Air-en...
