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(biāo)準(zhǔn)條件下進(jìn)行，確定砂漿強(qiáng)度等級。將3個試塊按1組進(jìn)行評價，3個試塊的平均值為砂漿試塊抗壓強(qiáng)度的平均值。對于三個測量值的值或更小值，當(dāng)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(qiáng)度值。當(dāng)兩個值的差值大于15%時，該試驗組的實(shí)驗結(jié)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(shù)量應(yīng)符合以下規(guī)定:不同強(qiáng)度等級的砂漿及相應(yīng)的砂漿試塊應(yīng)分別制作。試驗塊應(yīng)按機(jī)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(yīng)在相同的條件下進(jìn)行測試，以檢測每個施工階段的強(qiáng)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(qiáng)度等級的試件平均強(qiáng)度不得低于設(shè)計強(qiáng)度等級。2. 任何試驗塊的強(qiáng)度應(yīng)大于設(shè)計強(qiáng)度等級的75%。3.在實(shí)測工程中，如果砂漿試塊強(qiáng)度等級不合格，則該工程部分也不合格。在寒冷地區(qū)和潮濕環(huán)境中，砂漿試塊的強(qiáng)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.

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