Measuring concrete composition and characteristics - using vol. characteristics of compsn. of material and formulae defining pressure resistance and workability

摘要

A method of measuring the composition and characteristics of concrete involves using the vol. characteristics of the concrete composition such as admixture vol., feed material pore vol., adhesion water of the admix and the vol. of the cement paste as well as the further parameters of the output materials. - Formulae are given which define the press. resistance of the concrete and the workability of the fresh concrete from the above characteristics.
