【摘要】：为了控制墙面抹灰组分不合理造成墙面抹灰出现空鼓、脱落、掉渣等问题,介绍了EDXRF法测定墙面抹灰组分的分析方法,建立了墙面抹灰成分配比与Ca特征X射线强度关系曲线,并验证了该方法的可行性和稳定性。实验结果表明:该方法对于水泥含量较低的样品比较有效,对于水泥含量较高的样品误差偏大;对于水泥含量较低的样品,测量结果相对误差不大于3.30%,对于水泥含量较高的样品,测量结果相对误差不大于8.89%;时隔一个月后重复测量发现,低含量水泥样品的相对误差还是小于高水泥含量样品的相对误差,且测得的相对误差均在原来的误差之内,该方法具有较好的稳定性。
[Abstract]:In order to control the problems of wall plastering such as hollow, falling off and falling slag caused by unreasonable composition of wall plastering, this paper introduces the analytical method of determining the composition of wall plastering by EDXRF method, and establishes the relationship curve between the composition ratio of wall plastering and the characteristic X-ray intensity of Ca. The experimental results show that the method is effective for the samples with low cement content, and the error is larger for the samples with higher cement content, and for the samples with low cement content, the experimental results show that the method is effective for the samples with low cement content, and the error is larger for the samples with higher cement content. The relative error of the measurement result is not greater than 3.30. For the sample with high cement content, the relative error of the measurement result is not greater than 8.89. The relative error of low content cement sample is still smaller than that of high cement content sample, and the measured relative error is within the original error. This method has good stability.
