水泥穩(wěn)定碎石的強(qiáng)度檢測(cè)標(biāo)準(zhǔn)主要涉及無(wú)側(cè)限抗壓強(qiáng)度，這一標(biāo)準(zhǔn)通常遵循國(guó)家的相關(guān)規(guī)定和試驗(yàn)方法。以下是對(duì)水泥穩(wěn)定碎石強(qiáng)度檢測(cè)標(biāo)準(zhǔn)的詳細(xì)解讀：

　　The strength testing standards for cement stabilized crushed stone mainly involve unconfined compressive strength, which usually follows relevant national regulations and testing methods. The following is a detailed interpretation of the strength testing standards for cement stabilized crushed stone:

　　一、強(qiáng)度檢測(cè)要求

　　1、 Strength testing requirements

　　強(qiáng)度指標(biāo)：

　　Intensity index:

　　水泥穩(wěn)定碎石的強(qiáng)度主要通過(guò)無(wú)側(cè)限抗壓強(qiáng)度來(lái)評(píng)價(jià)。不同級(jí)別的水泥穩(wěn)定碎石在特定齡期（如28天）下的無(wú)側(cè)限抗壓強(qiáng)度有不同的最小值要求。例如，國(guó)家標(biāo)準(zhǔn)GB/T 17671-1999《水泥穩(wěn)定砂石料》中規(guī)定了不同級(jí)別水泥穩(wěn)定碎石的抗壓強(qiáng)度標(biāo)準(zhǔn)，其中低于1.5MPa的級(jí)別可用于基層，高于1.5MPa的級(jí)別適用于路面結(jié)構(gòu)。

　　The strength of cement stabilized crushed stone is mainly evaluated by its unconfined compressive strength. Different levels of cement stabilized crushed stone have different minimum requirements for unconfined compressive strength at specific ages (such as 28 days). For example, the national standard GB/T 17671-1999 "Cement Stabilized Sand and Gravel" specifies the compressive strength standards for different grades of cement stabilized crushed stone, with grades below 1.5 MPa applicable to the base layer and grades above 1.5 MPa applicable to the pavement structure.

　　試驗(yàn)方法：

　　Test method:

　　無(wú)側(cè)限抗壓強(qiáng)度試驗(yàn)是檢測(cè)水泥穩(wěn)定碎石強(qiáng)度的常用方法。該試驗(yàn)將標(biāo)準(zhǔn)試樣在規(guī)定的濕度條件下進(jìn)行壓縮，測(cè)量試樣破壞前的最大荷載，并計(jì)算出其抗壓強(qiáng)度值。

　　Unconfined compressive strength test is a commonly used method for testing the strength of cement stabilized crushed stone. This experiment compresses the standard specimen under specified humidity conditions, measures the maximum load before the specimen fails, and calculates its compressive strength value.

　　二、檢測(cè)步驟與注意事項(xiàng)

　　2、 Testing steps and precautions

　　試驗(yàn)準(zhǔn)備：

　　Preparation for the experiment:

　　按照規(guī)定的方法制備試件，并在標(biāo)準(zhǔn)養(yǎng)護(hù)條件下進(jìn)行養(yǎng)護(hù)，直至達(dá)到規(guī)定的齡期。

　　Prepare the specimens according to the prescribed method and cure them under standard curing conditions until the specified age is reached.

　　準(zhǔn)備試驗(yàn)所需的儀器設(shè)備，如萬(wàn)能材料試驗(yàn)機(jī)、游標(biāo)卡尺、電子天平等。

　　Prepare the necessary instruments and equipment for the experiment, such as universal material testing machine, vernier caliper, electronic balance, etc.

　　試驗(yàn)步驟：

　　Experimental steps:

　　將試件從養(yǎng)護(hù)環(huán)境中取出，并用軟布吸去試件表面的水分。

　　Remove the specimen from the curing environment and use a soft cloth to absorb any moisture from the surface of the specimen.

　　測(cè)量試件的高度和直徑，并記錄數(shù)據(jù)。

　　Measure the height and diameter of the specimen and record the data.

　　將試件放置在萬(wàn)能材料試驗(yàn)機(jī)的球形支座上，并進(jìn)行壓縮試驗(yàn)。

　　Place the specimen on the spherical support of the universal material testing machine and conduct a compression test.

　　記錄試件破壞時(shí)的最大壓力，并根據(jù)公式計(jì)算出無(wú)側(cè)限抗壓強(qiáng)度。

　　Record the maximum pressure at which the specimen fails and calculate the unconfined compressive strength according to the formula.

　　注意事項(xiàng)：

　　Attention:

　　在試驗(yàn)過(guò)程中，應(yīng)保持加載速率恒定，避免過(guò)快或過(guò)慢導(dǎo)致試驗(yàn)結(jié)果不準(zhǔn)確。

　　During the experiment, the loading rate should be kept constant to avoid inaccurate test results caused by being too fast or too slow.

　　同一組試件的試驗(yàn)結(jié)果應(yīng)進(jìn)行統(tǒng)計(jì)分析，剔除異常值，并計(jì)算強(qiáng)度平均值和變異系數(shù)。

　　The test results of the same group of specimens should be statistically analyzed, outliers should be removed, and the average strength and coefficient of variation should be calculated.

　　如試驗(yàn)結(jié)果不符合要求，應(yīng)重新制備試件并進(jìn)行試驗(yàn)。

　　If the test results do not meet the requirements, the specimens should be prepared again and tested.
