特细砂混凝土在奶牛场建设项目中的应用研究

Research on the Application of Ultra-Fine Sand Concrete in Dairy Farm Construction Projects

摘要: 为满足现代奶牛场建设对混凝土工程质量的要求，本文以农垦乳业股份有限公司红崖子第三奶牛场建设项目–后备牛舍地面工程为研究对象，系统开展了C30特细砂混凝土的原材料选择、配合比设计、性能检测及工程应用研究。通过试验确定了优化的C30混凝土配合比。性能检测结果表明，该配合比混凝土氯离子和碱含量控制在规范允许范围内，28 d抗压强度达到42.36 MPa，强度达标率141.21%；坍落度实测值165 mm，满足设计要求的150 ± 30 mm范围。该C30特细砂混凝土具有良好的工作性能和力学性能，完全满足奶牛场后备牛舍地面工程的使用要求，为类似农业建筑工程的混凝土应用提供了可靠的技术参考。

Abstract: In order to meet the requirements of modern dairy farm construction for the quality of concrete engineering, this article takes the construction project of Hongyazi Third Dairy Farm of Nongken Dairy Co., Ltd. - Reserve Cowshed Ground Engineering as the research object, and systematically conducts research on the selection of raw materials, mix design, performance testing, and engineering application of C30 ultra-fine sand concrete. The optimized C30 concrete mix ratio was determined through experiments. The performance test results show that the chloride ion and alkali content of the concrete with this mix ratio is controlled within the allowable range of the specifications, and the compressive strength at 28 days reaches 42.36 MPa, with a strength compliance rate of 141.21%; The measured slump value is 165 mm, which meets the design requirements within the range of 150 ± 30 mm. The C30 ultra-fine sand concrete has good workability and mechanical properties, fully meeting the requirements for the use of ground engineering in the reserve cowshed of dairy farms, and providing a reliable technical reference for concrete applications in similar agricultural construction projects.
