Guide For Concrete Floor And Slab Construction

Summary

FOREWORD The quality of a concrete floor or slab is highly dependent on achieving a hard, durable surface that is flat, relatively free of cracks and at the correct grade and elevation. Failure to address this issue can contribute to undesirable wear surface characteristics such as cracking, poor wear resistance, dusting, scaling, high or low spots and a poor drainage, as well as an increased risk of curling. Concrete floor slabs using portland cement, regardless of sag, will begin to experience volume reduction upon placement. Therefore, each homeowner should be advised by both the designer and the contractor that it is quite normal to expect a certain amount of cracking and warping on every project, and that such an occurrence does not necessarily reflect negatively on floor design competence or quality. of its construction. 1.2 Refer to the latest edition of ACI 360 for a detailed discussion of shrinkage and waviness of slabs on grade. It emphasizes aspects of construction such as site preparation, concreting materials, proportions of concrete mix, fabrication of concreting, construction of joints, load transfer through joints, stripping and curing procedures.

Floor Slabs

Descriptions and guidelines are provided in the following sections:

Finishing of floor coverings

Concrete floor slab

Aggregated drainage layers

Under-slab vapor barrier

Waterproofing membrane

protection board

Prefabricated drainage layers

Finishing of floor coverings

Depending on the interior space, the finish flooring can be the exposed concrete surface itself or various floor coverings such as wood, vinyl flooring or carpeting. Apps

There are two main types of basic floor detailing which are distinguished by the requirements of the interior space and the exterior environment:

Base Floor Slab—Typical System

Base Floor Slab—Sealed System

Basic Floor Slab—Typical System

A typical base floor slab where the design criteria includes control of moisture vapor transmission into the interior space but does not concern itself with waterproofing the base floor due to hydrostatic pressure loads may be called an imperfect barrier system. System components include a well-compacted but well-drained granular aggregate capillary break system placed directly over unexcavated, undisturbed soil. The granular aggregate capillary break system provides a collection zone for moisture to accumulate and dissipate as well as firm support for slab loads.
