Contraction Joints Sample Clauses

Contraction Joints. Contraction joints shall be provided at intervals of twenty (20) meters or less except as otherwise mentioned on the drawings or as directed by the Engineer. The contraction joint shall be a straight line perpendicular to the flow direction and, where it is necessary on such horizontal surfaces as floors, shall be parallel to the flow direction.

Contraction Joints. The position of construction joints will be as specified in the drawings by the designer. If there is a need on site to revise any specified position /or/ to have additional construction joints the proposed positions should be agreed with the Engineer. Full structural continuity must be assumed in design at a construction joint. Reinforcement will be fully continuous across the joint, and the concrete is taken to be as nearly monolithic as possible. The concrete at the joints should be bonded with the one subsequently placed against it, without provision for relative movement between the two. Concrete should not be allowed to run to a feather edge, and vertical joints should be formed against a stop end. Particular care should be taken when framing the joint. The surface of the first pour should be roughened to increase the bond strength and to provide aggregate interlock. With horizontal joints, the joint surface should be roughened without disturbing the coarse aggregate particles, by spraying the joint surface approximately 2h to 4h after the concrete is placed, with a fine spray water and/or brushing with stiff brush. Vertical joints can be treated similarly, if the use of a retarder on the top is authorised, to enable the joint surface to be treated after the stop end has been removed. If the joint surface is not roughened until the concrete has hardened, the larger aggregate particles near the surface should be exposed by sand blasting or by applying a scaling hammer or other mechanical advice. Care should be taken that the joint surface is clean immediately before the fresh concrete is placed against the old one. It may need to be dampened prior to the new concrete being placed, to prevent excessive loss of mix water into it by absorption. Particular care should be taken in placing of new concrete close to the joint to ensure that it has adequate fines content and is fully compacted and dense. N.B. When instructed by the Engineer in designing construction joints for retaining aqueous liquids it is necessary to incorporate waterstops in properly constructed joints. Construction joints shall be formed only in the positions shown in the drawings or indicated by the Engineer and concreting shall be carried out continuously between and up to joints. All intersections of construction joints, permanently exposed, shall be made absolutely straight and level or plumb and matching with adjacent members. Construction joint shall be formed at right angles to th...

Contraction Joints. For matching placed items, contraction joints shall be cut to a minimum depth of one-and-one-half (1%") inches. Sawing shall begin as soon as the concrete has hardened to the degree that excessive xxxxxxxx will not occur. Sawing shall progress in the same direction and sequence as the concrete placement. Every third joint shall be sawed first, then saw intermediate joints.

Contraction Joints. Contraction joints serve to provide for volumetric shrinkage of monolithic concrete and for movement shrinkage cracks else where in concrete. Prior to application of wax based curing compound to contraction joints, the surfaces of all joints shall be cleaned thoroughly of accretion of concrete or other foreign material by scraping, chipping or other means approved by the Engineer-in-Charge. Water stops, reinforcing bars and other embedding items shall be free of curing compound when adjoining concrete is placed.
