Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] The invention provides a method and a measuring system for measuring the water content in construction sand, which are used to quickly measure the water content of sand in construction, and solve the time-consuming and labor-intensive defect of traditional drying method for sand measurement. The invention can obtain the water content of the sand only by weighing twice, the measuring method is fast, the measuring efficiency is significantly improved, and the measuring method and system are simple to realize, have the effect of energy saving, and greatly save the cost. The measurement method and measurement system for the water content in the construction sand of the present invention will be described below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , shows the system diagram of the measurement system of th...

Abstract

The invention relates to a measuring method for water content in construction sand. The method includes the steps that a measuring container with a set volume is provided; sand with set weight is added into the measuring container, and the total mass of the measuring container and the added sand at the moment are weighed to obtain mass m1; the measuring container is filled with water, and the total mass of the measuring container, the sand and the filled water is weighed to obtain mass m2; the mass of the filled water is calculated to obtain mass mjw; the water content in the sand is obtain through a water content calculation formula. The water content in the sand can be obtained through two-time weighing, and the implement method is easy, saves measuring time, energy and cost, improves measurement efficiency and provides large benefits for a construction site. Compared with a drying method, time needed for measuring is greatly shortened, and the water content of the sand can be obtained fast.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a method and system for measuring moisture content in construction sand. Background technique [0002] The moisture content of sand in building materials is usually measured before use. The method of measurement is usually to put the weighed sand and container into an oven and dry them to the horizontal weight, then weigh the dried sand and container again, and record After weighing the value, the moisture content of the sand is calculated by a mathematical formula. Such a method generally needs to be dried for 4 to 5 hours, which is time-consuming and labor-intensive. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a method and a measurement system for measuring the moisture content of construction sand, and solve the problem of time-consuming and labor-intensive drying measurement of the moistur...
