B. Samples and Tests of I:Iateria.ls: Where, in the opinion of the Engineer, or as called for in the apeoifioations, tests of materials are necessary, suoh teats will be made at the expense of the City unless otherwise provided.

Join In The following paragraph shall apply to thin slabs alls at points where thin slabs are deposited without ring forms on both faces: Concrete shall be thoroughly tamped and puddled around einforcing and into position. iting Concrete Slabs: On the bottom and sloping slabs of structures, before iting concrete, the earth shall be hand dressed to a bearing. If excavation is carried below grade, it be backfilled with concrete. Before depositing such slabs where shown on the plans, arth surface on which the concrete is to be laid shall vered with a layer of sisal kraft paper, or an ved equal, well lapped and fastened firmly in position. oncrete shall be deposited on top of this waterproof This waterproof paper shall conform with General New Concrete to Old: Before depositing concrete against that which has set, the arms shall be retightened. Smooth surfaces of the set oncrete shall be roughened to a depth of one -half (1/2) inch thoroughly cleaned of foreign matter and laitance and aturated with water. To insure bond, the new concrete placed in contact with hardened or partially hardened concrete shall contain an excess of mortar. If required,• the leaned and saturated surfaces of the hardened concrete, incl ding vertical and inclined surfaces, shall first be cove ed with a sprinkling of neat cement, against which the new concrete shall be placed. Construction joints shall be located as approved by ngineer, and formed so as to least impair the appearance trength of the structures. the and no c Unless specified otherwise in writing by the Engineer, ncrete shall be deposited against earth side walls. 1 Where it is desired to cast concrete against forms whic are to be left in place, such process shall be subject to t e approval of the Engineer. Remopal of Water: Water shall be removed from the excavation before the conc ete is deposited. Any flow of water into the excavation shal be directed through proper side drains to a sump, or removed by other approved methods which avoid washing the '!reshly deposited concrete. After the concrete has thoroughly hardened, water vent pipes shall be filled by grouping. Curi}�g Concrete: ( Curing the concrete on this project is considered to be of major importance. Exposed surfaces of the concrete shall be kept wet cont nuously for a period of not less than seven (7) days afte the time of depositing concrete.
