A Calculation Method of Specific Heat of Masonry

Abstract

The invention provides a computing method of masonry specific heat. The method comprises the following steps that a small amount of regular brick masonry is taken, the mass m0 is weighted out; according to brick quantities of unit cube brick masonry and the volume v0 of the taken brick masonry provided by a construction unit, the mass of bricks of the above-mentioned taken brick masonry is determined; the water content mw of the taken brick masonry is measured through a drying method; the specific heat of dry mortar obtained after the brick masonry is dried is determined; the specific heat of the brick masonry is obtained finally. The computing method of the masonry specific heat has the advantages that the specific heat of the masonry is calculated from the perspective of the material composition of the masonry, the computing method is visual, and operation is easy and convenient. When the computing method is applied to engineering practice, the specific heat of the masonry can be determined more rapidly, and very important significant for energy saving is achieved.

Description

technical field [0001] The invention relates to a method for calculating the specific heat of masonry, which is mainly described by taking brick masonry as an example. This method is applicable to the specific heat calculation of all masonry such as stone masonry and block masonry. Significant significance to building energy-saving design. Background technique [0002] Masonry structure is widely used in our country because of its simple construction process, low technical requirements and easy access to materials. With the continuous development of economy and society and the improvement of human living standards, people have higher and higher requirements for the aesthetics and comfort of buildings. Determining the thermal physical parameters of building materials is more and more important to the design and scientific research of actual projects. more important. [0003] Specific heat is the energy absorbed or released when a unit mass of a substance changes a unit tem...

Problems solved by technology

[0005] The above-mentioned experimental methods are complicated to operate, inconvenient to equip with instruments, have high requirements on operators and the environment, and there are unavoidable heat losses, which are likely to cause large experimental errors.

Therefore, it is less applicable in construction engineering
