Time of Setting. - The initial set of the cement shall be in not less than 30 minutes, when mixed neat with the smallest possible amount of water at the temperature at which it flows from the tap in the water system of the City of Huntington Beach, but hard set must develop in not less than one hours nor more than ten hours. Tensile Strength. - Briquettes one inch square in section shall attain at least the following tensile strengths and shall show no retrogression within the periods specified: After twenty-four hours in moist air, neat, 150 pounds per square inch. After seven days (briquettes to remain in moist air one day, in water six days), neat, 450 pounds per square inch; three (3)parts sand to one (1)part cement, 150 pounds per square inch. After twenty-eight days (briquettes to remain in moist air one day, in water twenty-seven days), neat, 550 pounds per square inch; three parts sand to one part cement, 200 pounds per square inch. ORD. 028 2 Soundness. - Test parts of neat cement about three inches in diameter, one-half inch thick at the center and tapering to a thin edge, shall be kept in moist air for a period of twenty-four hours.
