Embodiment

[0010] Described test method comprises the steps:

[0011] (1) Select detection points in the detected area: that is, the most edge point in the detection area is 2-3 meters away from the rolling sideline, and the distance between the measurement points is 8-10 meters, arranged in a plum blossom shape;

[0012] (2) Test process: Use a small shovel to plan a hole on the test point of the newly compacted dry hard concrete, weigh the dry hard concrete material taken out of the planed hole, and record the weight; spread it on the freshly planed concrete with a plastic bag In the pit, use a measuring cup to take water and pour it into the plastic bag in the planing pit until the planing pit is filled with water, and record the amount of water poured in;

[0013] (3) Calculation of the compaction coefficient: the ratio of the quality of the dry hard concrete material taken out of the planing pit to the amount of water poured into the planing pit is the actual dry density of the dry ...

Abstract

The invention relates to a dry concrete, in particular to a method for testing a compaction coefficient of dry concrete, belonging to the technical field of building construction. The testing method comprises the following steps of: selecting a detection point at a tested region; digging and taking dry concrete to weigh; recording weight; filling a plastic bag filled with water in a dug pit; filling the pit; and recording quantity of filled water, wherein the ratio of the weight of the dry concrete taken from the dug pit to the quantity of water filled in the dug pit is dry density of the dry concrete which is actually achieved by compaction, the ratio of the dry density of the dry concrete which is actually achieved by compaction to the maximum dry density of a test piece obtained by a tamping experiment is the compaction degree, and the compaction degree in percentage form is the actual compaction coefficient.

Description

technical field [0001] The invention relates to dry hard concrete, in particular to a method for testing the compaction coefficient of dry hard concrete, and belongs to the technical field of building construction. Background technique [0002] On the building construction site, the construction quality of dry hard concrete has a great relationship with the compaction coefficient. It is difficult for existing technologies to accurately reflect the real compaction situation. This often leads to the out-of-control of the compaction situation in the construction process, which also leads to the out-of-control of the dry hard concrete construction quality. The compaction coefficient refers to the ratio of the actual dry density of the dry hard concrete after compaction during construction to the maximum dry density of the sample obtained from the compaction experiment. The compaction quality of dry hard concrete is expressed by the degree of construction compaction K (%). The...
