水泥穩定碎石的強度檢測標準主要涉及無側限抗壓強度，這一標準通常遵循國家的相關規定和試驗方法。以下是對水泥穩定碎石強度檢測標準的詳細解讀：

　　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、強度檢測要求

　　1、 Strength testing requirements

　　強度指標：

　　Intensity index:

　　水泥穩定碎石的強度主要通過無側限抗壓強度來評價。不同級別的水泥穩定碎石在特定齡期（如28天）下的無側限抗壓強度有不同的最小值要求。例如，國家標準GB/T 17671-1999《水泥穩定砂石料》中規定了不同級別水泥穩定碎石的抗壓強度標準，其中低于1.5MPa的級別可用于基層，高于1.5MPa的級別適用于路面結構。

　　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.

　　試驗方法：

　　Test method:

　　無側限抗壓強度試驗是檢測水泥穩定碎石強度的常用方法。該試驗將標準試樣在規定的濕度條件下進行壓縮，測量試樣破壞前的最大荷載，并計算出其抗壓強度值。

　　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、檢測步驟與注意事項

　　2、 Testing steps and precautions

　　試驗準備：

　　Preparation for the experiment:

　　按照規定的方法制備試件，并在標準養護條件下進行養護，直至達到規定的齡期。

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

　　準備試驗所需的儀器設備，如萬能材料試驗機、游標卡尺、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.

　　試驗步驟：

　　Experimental steps:

　　將試件從養護環境中取出，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.

　　測量試件的高度和直徑，并記錄數據。

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

　　將試件放置在萬能材料試驗機的球形支座上，并進行壓縮試驗。

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

　　記錄試件破壞時的最大壓力，并根據公式計算出無側限抗壓強度。

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

　　注意事項：

　　Attention:

　　在試驗過程中，應保持加載速率恒定，避免過快或過慢導致試驗結果不準確。

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

　　同一組試件的試驗結果應進行統計分析，剔除異常值，并計算強度平均值和變異系數。

　　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.

　　如試驗結果不符合要求，應重新制備試件并進行試驗。

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

　　三、強度檢測標準的實際應用

　　3、 Practical Application of Strength Testing Standards

　　工程質量驗收：

　　Engineering quality acceptance:

　　在道路工程中，水泥穩定碎石的強度檢測是工程質量驗收的重要環節。通過檢測無側限抗壓強度，可以判斷水泥穩定碎石的質量是否符合設計要求。

　　In road engineering, the strength testing of cement stabilized crushed stone is an important part of engineering quality acceptance. By testing the unconfined compressive strength, it can be determined whether the quality of cement stabilized crushed stone meets the design requirements.

　　施工控制：

　　Construction control:

　　在施工過程中，通過定期檢測水泥穩定碎石的強度，可以及時發現施工中的問題并采取相應措施進行糾正。這有助于確保施工質量和工程進度。

　　During the construction process, by regularly testing the strength of cement stabilized crushed stone, problems can be identified in a timely manner and corresponding measures can be taken to correct them. This helps ensure construction quality and project progress.

　　科研與改進：

　　Research and improvement:

　　綜上所述，水泥穩定碎石的強度檢測標準是一個復雜而重要的過程，涉及多個方面的要求和注意事項。通過遵循這些標準和要求，可以確保水泥穩定碎石的質量符合設計要求，并保障道路工程的安全和穩定性。

　　In summary, the strength testing standards for cement stabilized crushed stone are a complex and important process that involves multiple requirements and precautions. By following these standards and requirements, it is possible to ensure that the quality of cement stabilized crushed stone meets design requirements and guarantees the safety and stability of road engineering.
