贫砼是由集料与一定水泥和水拌和而成的砼,其水泥用量较普通砼低,也称经济砼。与水泥稳定级配碎石、二灰碎石等常用半刚性基层材料相比,贫砼具有较高的强度、刚度、抗冲刷性和耐久性能。本文结合白音花至霍林河一级公路贫混凝土基层施工的经验,谈了贫砼基层施工质量控制的要点。 Poor concrete is aggregated with a certain amount of cement and water from the mixing of concrete, the cement dosage lower than ordinary concrete, also known as economic concrete. Compared with the commonly used semi-rigid base materials, such as stabilized graded gravel and lime-fly ash, lean concrete has high strength, stiffness, impact resistance and durability. Based on the experience of Baiyinhua to the construction of lean concrete in the first grade of Huolinhe Road, the paper points out the key points in the construction quality control of the lean concrete base.
