NOTE.—Cement or lime may be tendered for separately.
- All cement supplied under this item shall be Portland cement of New Zealand manufacture, and shall be equal in quality to the best English-made Portland cement. It shall be capable, when mixed with water and moulded into briquettes, of bearing without fracture a tensile stress of 350 lb. to the square inch on briquettes 1 in. in sectional area at seven days after gauging and immersion in water, and 450 lb. per square inch at twenty-eight days after being similarly gauged and immersed in water. The briquettes for testing the tensile strength of the cement shall be moulded of approved shape, so as to have a section in the breaking-part of 1 in. by 1 in.; they shall be immersed in water twenty-four hours after gauging, and be kept in the water for the remaining portion of the seven days or twenty-eight days, as the case may be, and shall be tested in a cement-testing machine to be approved by the Engineer. The cement shall also be tested for soundness by forming thin pats of cement, gauged with water, on glass, set in water immediately after gauging, and also set in air: these pats shall show no signs of cracking, warping, tendency to separate from the glass, or other signs of unsoundness within seven days after gauging, and shall be of a uniform grey colour throughout. All cement shall be ground to such a degree of fineness that no sample shall leave a greater residue than ¼ per cent. on a sieve of No. 35 S.W.G. wire with 2,500 meshes per square inch, nor a greater residue than 4 per cent. on a sieve of No. 39 S.W.G. wire with 5,776 meshes per square inch. No cement will be accepted that will not stand the above tests.
