초록 ▼

A design optimization process used to determine the proportions of sand, cement, coarse aggregate, water, fly ash, water reducers, air entraining agents and fillers needed to produce a concrete mixture that has desired strength and slump properties and a minimal cost. The optimization process comprises a combination of models that accurately reflect the properties of a concrete mixture based on the properties of its individual components. The process is further capable of optimizing the durability of the cementitious mixture and of accurately calculating the expected yield of the mixture.

대표청구항 ▼

A method for designing a cementitious mixture by means of a computer-implemented design optimization process without trial and error testing of a final hydrated cementitious mixture, the method comprising the steps of: (a) providing a batch of hydraulic cement and a batch of aggregate to be mixed together to form a final hydrated cementitious mixture, the batch of hydraulic cement including a plurality of individual particles having an average diameter particle size and a particle packing density and the batch of aggregate including a plurality of individual particles having an average diameter particle size and a particle packing density; (b) selecting a target slump for the final hydrated cementitious mixture prior to hardening and a target strength for the final hydrated cementitious mixture after curing and thereafter inputting to a central processing unit (CPU) the target slump and target strength; (c) measuring the average diameter particle size of the individual particles in the batch of hydraulic cement and thereafter inputting to the CPU the average diameter particle size of the individual particles in the batch of hydraulic cement; (d) measuring the particle packing density of the batch of hydraulic cement and thereafter inputting to the CPU the particle packing density of the batch of hydraulic cement; (e) measuring the average diameter particle size of the individual particles in the batch of aggregate and thereafter inputting to the CPU the average diameter particle size of the individual particles in the batch of aggregate; (f) measuring the particle packing density of the batch of aggregate and thereafter inputting to the CPU the particle packing density of the batch of aggregate; (g) designing a dry cementitious mixture from the batch of hydraulic cement and batch of aggregate, the dry cementitious mixture having a concentration ratio of hydraulic cement and aggregate, and thereafter inputting to the CPU the concentration ratio of hydraulic cement and aggregate in the dry cementitious mixture; (h) the CPU calculating the particle packing density of the designed dry cementitious mixture based on: (1) the average diameter particle size of the individual particles in the batch of hydraulic cement; (2) the particle packing density of the batch of hydraulic cement; (3) the average diameter particle size of the individual particles in the batch of aggregate; (4) the particle packing density of the batch of aggregate; and (5) the concentration ratio of hydraulic cement and aggregate in the designed dry cementitious mixture; (i) the CPU calculating, based on the particle packing density of the designed dry cementitious mixture, an amount of water that when mixed with the designed dry cementitious mixture yields a designed hydrated cementitious mixture having the target slump; (j) the CPU calculating, based on the amount of water calculated in step (i), a calculated strength for the designed hydrated cementitious mixture after curing; (k) the CPU calculating the difference between the calculated strength for the designed hydrated cementitious mixture after curing and the target strength; and (l) the CPU altering the concentration ratio of hydraulic cement and aggregate in the designed dry cementitious mixture in order to design one or more subsequently designed dry cementitious mixtures and then repeating steps (h)-(k) for each of the one or more subsequently designed dry cementitious mixtures in order to identify one or more optimally designed hydrated cementitious mixtures having a strength after curing within an acceptable range of deviation with respect to the target strength.
