Description

Technical Field

[0001] This invention belongs to the field of building materials technology, and more specifically, relates to a method for full calculation and design of concrete mix proportions based on quantitative analysis. Background Technology

[0002] Concrete is an artificial stone material made by mixing cement as the main binder with sand, gravel, and, when necessary, chemical admixtures and mineral admixtures, in appropriate proportions, adding a certain amount of water, and then uniformly mixing, compacting, molding, and curing it. The concrete mix proportion refers to the specific quantitative relationship between the various components of concrete (cement, fly ash, mineral powder, sand, gravel, water, water-reducing agents, etc.).

[0003] The current ordinary concrete mix design is based on JGJ55-2011 "Specification for Mix Design of Ordinary Concrete". The design method has the following problems and defects: First, the water content. JGJ55 uses the table lookup method to obtain the water content of concrete mix design within the water-cement ratio of 0.4-0.8, which cannot be applied to mix design with low water-cement ratio, and the design has obvious limitations. Furthermore, when the fineness of sand changes, JGJ55 only provides adjustment methods of increasing water by 5-10 kg for "coarse sand" and decreasing water by 5-10 kg for "fine sand." However, the standard defines coarse and fine sand based on the range of fineness modulus, which is too broad. Even within the range of coarse (or fine) sand, if the fineness modulus changes, designers must rely on repeated experiments to find the appropriate water dosage, leading to a significant increase in the number of tests and labor costs. Secondly, regarding the sand ratio, JGJ55 also uses a lookup table method for the sand ratio, and only provides specific methods for determining the sand ratio under four conditions: water-cement ratio of 0.40, 0.50, 0.60, and 0.70. Moreover, the given sand ratio is a range, which is too wide. In actual production, even different sand ratios within the same range can cause huge differences in concrete workability and material costs. This usually requires skilled technicians to conduct a large number of experiments, and the number and effectiveness of the experiments heavily depend on the experience of the technicians. The results obtained by different personnel can vary drastically.

[0004] It is evident that current design methods for ordinary concrete are all based on the aforementioned industry standards. The sand ratio and water content are obtained through qualitative analysis and experience, which have some guiding significance within a certain range, but cannot cope with the current situation where frequent changes in raw materials necessitate timely adjustments to the mix proportion. Therefore, there is an urgent need for a design method that can quantitatively reflect the specific impact of changes in sand coarseness, aggregate particle size, and slump index on the sand ratio and water content of concrete mix proportions. This method should enable the rapid and accurate design of ordinary concrete mix proportions that meet strength and workability requirements based on the partial properties of raw materials. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a quantitative analysis-based method for the full calculation and design of concrete mix proportions. The calculation of sand ratio and water content is transformed from qualitative to quantitative analysis, accurately expressing the impact of changes in specific raw material properties on the concrete sand ratio under different water-cement ratios. This allows for faster and more accurate calculation of the actual concrete mix proportions for different materials, making cost and quality control more aligned with the practical application requirements of concrete mix proportions. The full calculation process for sand ratio and water content incorporates a slump design index for concrete, visualizing the workability of concrete in relation to the quantity and properties of raw materials. This allows for precise control of concrete workability while simultaneously controlling concrete strength. In terms of performance, this invention can quickly respond to the impact of material changes on the overall performance of concrete in actual production. The entire calculation process significantly reduces the reliance on the experience of concrete designers. Given the current scarcity of raw materials and the rapid changes in material properties in the concrete market, it can quickly and accurately calculate the precise mix proportions suitable for different raw materials, greatly reducing the number of tests and the test cycle, and improving the efficiency of concrete mix proportion design. This invention can quantitatively reflect the specific impact of changes in sand coarseness, aggregate particle size, and slump index on the sand ratio and water content of concrete mix proportions, enabling the rapid and accurate design of concrete mix proportions that meet the strength and workability requirements based on the partial properties of raw materials.
