MixSim is based on the researches and experience of Dr J D Dewar, of J D Dewar Consultancy, United Kingdom.
The aim of MixSim is to simulate the laboratory concrete mix design process in the computer enabling designs for properties of fresh and hardened concrete to be made more comprehensively, faster and more accurately on the basis of materials test data and only the minimum of concrete data, as may be essential for determination of strength.
Using MixSim, concrete designs may be prepared combining as many as 3 cementitious components, 3 fine aggregates or fillers and 3 coarse aggregates together with 3 liquid admixtures. Account is taken of any required air entrainment, strength producing benefits of additions and water reducing benefits of plasticisers. Concretes are adjusted automatically for adequate cohesion. Provision is made for input of any concrete trials data for comparison purposes.
Output data from MixSim include tables and graphs relating to water demand, per cent fines, plastic density, compressive strength (cubes or cylinders) and batch quantities taking account of batch size, moisture contents of aggregates and specified slump.
MixSim meets the requirements of Part 4 of the Quality Scheme for Ready Mixed Concrete (QSRMC) Regulations.
