Concrete: Scientific Principles

The relationship between the water to cement ratio and strength is shown in the graph that follows. Figure 6: A plot of concrete strength as a function of the water to cement ratio. Low water to cement ratio leads to high strength but low workability. High water to cement ratio leads to low strength, but good workability.

Relationship between log response and clay mineralogy from a well (34/7-1) from the northern North Sea. (From Thyberg et al., 2000). The Pliocene and Pleistocene sediments contain a mixture of chlorite, illite and kaolinite indicating a cold climate. They are more compacted than the underlying Eocene smectitic sediments deposited in a warm climate.

Concrete and Sustainability - GreenSpec

• In around 2002 researchers quantified the advantages in the relationship between 'heavy' concrete based construction and the use of thermal mass. This is likely to be useful in the future in helping to control indoor temperatures and in particular reduce the rise in instances of overheating in buildings.

Conglomerate: Sedimentary Rock - Geology

After compaction, the precipitation of a chemical cement between the grains will bind the sediment into a rock. Breccia is a rock that is similar to conglomerate; however, the clasts in breccia are angular in shape rather than rounded like in conglomerate. The shape of the clasts is the only physical difference between conglomerate and breccia

Matrix (geology) - Wikipedia

The matrix or groundmass of a rock is the finer-grained mass of material in which larger grains, crystals or clasts are embedded. The matrix of an igneous rock consists of finer-grained, often microscopic, crystals in which larger crystals (phenocrysts) are embedded. This porphyritic texture is indicative of multi-stage cooling of magma. For
