ABSTRACT
In this section, the results of laboratory tests of aggregates, mortar and concrete are compared with the results of computer simulations utilising the theory of particle mixtures, as follows
• Aggregate voids ratio diagrams 31 materials combinations of single sized or multi-sized aggregates
• Cement-sand mortar 6 trials of mortars • Concrete Series 1 60 trials covering 12 materials
combinations • Concrete Series 2 92 trials covering 4 materials
combinations with and without plasticising or air entraining admixtures
• Concrete Series 3 5 trials with fly-ash 6 trials with ground granulated slag
6.1 Aggregate mixture trials
6.1.1 Method
The following method applied to all experimental work with aggregates. 1. Bulk densities were measured in the oven-dry uncompacted (loosely
poured) condition using a metal cylinder approx 0.007m3 capacity, generally following the method of BS 812:1995.1
2. The bulk density of the coarser material was measured first and the quantity required to fill the container was then used for tests of mixtures.
