Abstract: Building materials are important elements that aff ect the overall quality of construction projects. If building materials do not meet the standard, it will greatly affect the safety of buildings and the exertion of use functions, which needs to give full play to the value of material testing and experiment. With the continuous development of the construction industry, the development of building materials is also changing with each passing day, showing a development trend in full swing. For some new energy-saving and environmental protection materials, many testing work can not effectively obtain accurate testing results, which also reflects some obvious problems existing in the testing experiment of building engineering materials to a certain extent. Therefore, combined with the practical significance of building engineering material testing experiment, starting with the key points of common building engineering material testing experiment, this paper will discuss the common problems of building engineering material testing experiment and the measures to improve the quality of building engineering material testing experiment, hoping to attract jade by throwing bricks and help relevant people, Help improve the quality of material testing experiment.
