CONSTRUCTION SPECIFICATION FOR CONCRETE SIDEWALK

This specification covers the requirements for the construction of concrete sidewalks. 351.01.01 Specification Significance and Use This specification is written as a municipal-oriented specification. Municipal-oriented specifications are developed to reflect the administration, testing, and payment policies, procedures, and practices of many Subgrades and Subbases for Slabs| Concrete 22.11.2017· Almost 20 years ago, Concrete Construction investigated the effect of using a layer of loose (uncompacted) sand directly beneath a concrete slab and concluded that this practice contributed to "more later-age cracks and poorer joint performance." Here are the reasons not to use a sand layer: · Difficult to maintain a flat, level sand surface during concrete placement · Difficult to Cement Concrete - Types of Sand: Uses, Based on the grain size of the particle, sand is classified as Fine Sand (0.075 to 0.425mm), Medium Sand (0.425 to 2mm), and Coarse Sand (2.0 mm to 4.75mm) Based on origin, sand is classified as Pit sand, River sand, Sea sand, and manufactured sand.
