... conclusions if applied to cohesive material which did not obey the primary law of resistance to shear which formed the basis of Rankine s theory. Moisture in sand caused the grains to adhere to each other, and this had the effect of increasing the supporting power a t or near the surface. Anyone who had...

.... Reviewing the history of cement-testing, and the experimental researches connected with it, the conclusion seems almost inevitable that neither of the systems a t present in generaluse-one depend- ing on the cohesive strength of neat cement, the other on that of a mixture of cement and sand-are likely...

... apart, measuring the strain as carefully as possible. I n these experiments he found it advisable to make a distinction between cohesion and adhesion. Cohesion was the quality which made the particles of a substance stick together between themselves ; adhesion was the force which unitedthematerialto...

Daily trials of the strength of the cement are made by moulding it into bricks, (vide Appendix, Experiments on Cohesion, Fig. 3, pp. 500and 501,)which in twenty-four hours after settinga,re exposed to rupture beyxtension...
