Study On Performance Optimization Of Glazed Hollow Bead Insulation&Bearing Block And Energy Consumption Analysis On The Masonry Structure

At present, the implementation of the national policy of building energy conservation has become an important issue in the field of civil engineering. The glazed hollow bead insulation concrete, as a new type of building materials, is by adding a certain amount of glazed hollow bead and additive to the ordinary concrete, so that the utility model has the concrete physical mechanics performance, but also has the thermal insulation performance. On the theory basis of the glazed hollow bead insulation concrete, we can put forward glazed hollow bead insulation load-bearing block, it is a kind of masonry materials has bearing and thermal insulation. Masonry structure has a long history, according to China’s current fundamental national condition, masonry structure is still one of the main form of the building structure in the next few years or even decades. Although the masonry structure is widely used in China, but its development is relatively slow. So the theoretical analysis and experimental study on performance optimization of glazed hollow bead insulation bearing block has important practical significance. Based on previous research results, the main research and relevant conclusion of this paper are as follows:1、In-depth study of the orthogonal test design theory, and on this basis the test scheme of the glazed hollow bead insulation load-bearing block is determined, namely with ceramic dosage、glazed hollow bead dosage、lime dosage、dry ash dosage as four factors and three levels orthogonal experiment.2. Make the required block of the test according to orthogonal test table, through the glazed hollow bead insulation load-bearing block mechanics test and thermal test measured the compressive strength and thermal conductivity of each test block, and processing the test results by using of orthogonal experimental design method. The results of two analysis methods are basically consistent, namely:the sequence of the Influence factors of glazed hollow bead insulation load-bearing masonry compressive strength are ceramic dosage�'glazed hollow bead dosage�'dry ash dosage�'lime dosage;The sequence of the influence factors of glazed hollow bead insulation load-bearing masonry thermal conductivity are glazed hollow bead dosage�'ceramic dosage�'lime dosage=dry ash dosage, Using the regression analysis method finally, the relationship equation between glazed hollow bead content and thermal conductivity is y=0.529-0.267x.3. According to the limit of the thermal performance of building envelopes under the65%energy saving standards, build model by using of residential energy consumption simulation software DeST-h,analysis the energy consumption status of glazed hollow bead insulation load-bearing block, obtained the number of hours of the natural room temperature of each room and heating season and air conditioning energy consumption status of the model, as well as the whole heating season, air conditioning season and annual energy consumption status of various systems and model building, in which, whether it is a single room、a single system or the whole building, all of the average energy consumption in heating season are less than65%energy-saving standards for buildings in Taiyuan City,15.4W/m2of heat consumption index.After the experimental research and analysis of the paper, the compressive and thermal insulation performance of glazed hollow bead insulation load-bearing block, and the simulation calculation of the masonry structure energy saving situation of glazed hollow bead insulation load-bearing block have good results,it provides the basis for the future research、optimization and the application of the block in the actual engineering.
