Experimental Research On Strength Of The Brickwork For A New Insulated Hollow Concrete Block

In order that the society can develop constently ,the government have set a target of energy-saving more than 50%.The test block is a new type of insulation to reach the goal of building energy-saving and the development of a set of energy-saving and loading into a new building materials. The aim of the pilot test is this block's mechanical properties and focus on the comparison with the general performance of the power block by the differences, and put forward the corresponding conclusions and recommendations.The tests include four parts :small sample compression, shear testing, wall-chip compression testing, anti-seismic static testing.Test the main reference of the basic mechanical properties of masonry and in practical application process should be the master of the performance. The trial produced a total of 24 samples of small resistance, shear 30 small sample, 2 compression chip wall, 6 to be anti-seismic static wall.The test results achieved, the results show that, in addition to shear strength value is lower than the norm, including the strength and value of the wall under pressure test with the formula put forward by the norms of good agreement. In addition, according to a standardized formula and the relevant test data from that seismic insulation block masonry shear strength of the calculation should be based on the existing norms provided by the calculation formula for calculating the carrying capacity and, in the calculation of the process of calculating The section is still used for load-bearing part of the block cross-section. In the experiment because the process of the role of the vertical load in the range of load-bearing block, this is more in line with the reality of the situation by force, and in the process of calculation is based on calculations for the load-bearing block section is still cross-section, by comparing the results and Test-value analysis, whether under pressure or shear, surface insulation are involved in the shear walls of the common, but limited role, to improve the bearing capacity is not large, it is proposed, in the heat of the block masonry wall Earthquake-shear strength of the calculation does not take into insulation and the role of surface decoration, and as a surplus of capacity to deal with.For shear strength value is lower than the norm, the author also carried out some research, and shear strength test methods to improve.
