抹面砂漿試塊的試驗規程和標準作業

來源：http://www.wavc.cn 日期：2020-02-27 發布人：

　　為了檢驗抹面砂漿的質量，在行業中有一個公認的慣例，那就是制造立方體砌塊。將砂漿按比例調制成模型后，可以測試砂漿的強度和其他性能。

　　In order to test the quality of plastering mortar, there is a recognized practice in the industry, which is to manufacture cube block. The strength and other properties of mortar can be tested after the mortar is proportioned into a model.

　　抹灰砂漿試塊的尺寸一般是固定的，一般是70.7mm的長方體。試驗在20℃、相對濕度大于90%的標準條件下進行，確定砂漿強度等級。將3個試塊按1組進行評價，3個試塊的平均值為砂漿試塊抗壓強度的平均值。對于三個測量值的值或更小值，當一個值與中值之差大于15%時，將值和更小值四舍五入。中值是測試集的抗壓強度值。當兩個值的差值大于15%時，該試驗組的實驗結果無效。

　　The size of plastering mortar test block is generally fixed, generally 70.7mm rectangular. The test is carried out under the standard conditions of 20 ℃ and relative humidity greater than 90% to determine the strength grade of mortar. Three test blocks are evaluated as one group, and the average value of three test blocks is the average value of compressive strength of mortar test block. For the maximum or minimum of three measurements, when the difference between one value and the median value is greater than 15%, round the maximum and minimum values. The median is the compressive strength value of the test set. When the difference between the two values is more than 15%, the experimental results of the experimental group are invalid.

　　另一方面，檢測組的數量應符合以下規定:不同強度等級的砂漿及相應的砂漿試塊應分別制作。試驗塊應按機理取樣，不能刻意篩選。2、對于主體建筑砂漿，至少三組試塊。一般建筑物及附屬建筑物，包括至少兩組測試大廈。3.測試塊應在相同的條件下進行測試，以檢測每個施工階段的強度。

　　On the other hand, the number of test groups shall meet the following requirements: mortar of different strength grades and corresponding mortar test blocks shall be made separately. The test block shall be sampled in accordance with the mechanism and shall not be selected deliberately. 2. For the main building mortar, at least three groups of test blocks shall be used. General and ancillary buildings, including at least two test buildings. 3. Test blocks shall be tested under the same conditions to detect the strength of each construction stage.

　　1. 同一強度等級的試件平均強度不得低于設計強度等級。2. 明顯試驗塊的強度應大于設計強度等級的75%。3.在實測工程中，如果砂漿試塊強度等級不合格，則該工程部分也不合格。在寒冷地區和潮濕環境中，砂漿試塊的強度水平一般提高1級。

　　1. The average strength of the test piece of the same strength grade shall not be lower than the design strength grade. 2. The minimum strength of any test block shall be greater than 75% of the design strength grade. 3. In the measured project, if the strength grade of mortar test block is unqualified, the part of the project is also unqualified. In cold area and humid environment, the strength level of mortar test block is generally increased by 1 grade.

　　以上是濟南抹面砂漿試塊的試驗規程和標準作業，感謝閱讀。

　　The above is the test procedure and standard operation of Jinan plastering mortar test block, thank you for reading.
