Problems solved by technology

[0002] During the construction of concrete pavement, because the concrete mixture mixing, transportation, paving and vibration compaction molding process are not strict, its strength is quite different from that under the laboratory test conditions. Therefore, there is a large variability in the concrete constructed on site

Embodiment Construction

[0022] The present invention will be described in further detail below.

[0023] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0024] A method for controlling variations in cement concrete pavement construction, comprising the steps of:

[0025] First, material selection: select high-quality cement, coarse aggregate, natural burning sand and admixtures;

[0026] For cement, the variety of cement should be strictly controlled. Portland cement or ordinary Portland cement should be used for road cement. By properly adjusting the mineral composition of cement, cement with less water demand, less shrinkage and high flexural strength can be obtained; at ...

Abstract

The invention discloses a variation control method for cement concrete pavement construction. The method includes the following steps: a step of material selecting, namely the step of selecting high-quality cement, coarse aggregate, natural sand and an additive; a step of stirring, namely the step of putting the coarse aggregate into a stirring machine, then successively putting the natural sand and the cement, adding the additive while adding the cement, adding water while stirring, and obtaining a mixture after uniform stirring; a step of transport, namely the step of transporting the mixture to a construction site; and a step of paving, namely the step of performing paving construction on the mixture. Compared with the prior art, the method can control the variation process of the concrete by setting the related parameters of each raw material; during stirring, the adding orders and stirring time of the raw materials can be strictly controlled, so that the concrete can be preventedfrom generating variation while good stirring effects can be achieved; and during the processes from the selecting of the raw materials to the final paving, the related parameters of the concrete aredetermined through scientific methods, so that the variation of the concrete can be effectively controlled, and good concrete paving effects can be finally achieved.

Description

technical field [0001] The invention relates to a construction method, in particular to a method for controlling variation in cement concrete pavement construction. Background technique [0002] During the construction of concrete pavement, due to the lax construction of concrete mixture mixing, transportation, paving and vibration compaction forming process, its strength is quite different from that under laboratory test conditions. Therefore, there is great variability in the concrete constructed on site. In view of this, the inventor obtained a method for controlling variation in cement concrete pavement construction after in-depth research. Contents of the invention [0003] The object of the present invention is to provide a method for controlling variation in cement concrete pavement construction, which can effectively control variation in cement concrete pavement construction and achieve good pavement effect. [0004] Above-mentioned technical purpose of the presen...
