ACI 523.1R
Guide for Cast-in-Place Low-Density Cellular Concrete
سال

چکیده: GENERAL
Definition of cellular concrete
Low-density cellular concrete (Fig. 1.1) is defined as concrete
made with hydraulic cement, water, and preformed foam to form a
hardened material having an oven-dry density of 50
lb/ft3 (800 kg/m3) or less. These mixtures
may include aggregate and other material components including, but
not limited to, fly ash and chemical admixtures.
This guide provides data and techniques pertaining to the
properties and applications of cast-in-place low-density cellular
concrete. Common applications of cast-in-place low-density cellular
concrete are on roof decks and geotechnical applications. On roof
decks, the material provides roofing base, thermal insulation, and
drainage slope for flat-roofed industrial and commercial buildings
(Fig. 1.2).
In geotechnical applications, the material is applied in thick
sections of cellular concrete with low compressive strengths (Fig.
1.3) for the replacement of poor soils, fills for abandoned
structures (pipelines), and cellular concrete fills designed,
mixed, and placed to meet specific job conditions and functional
requirements.
Definition of low-density, controlled low-strength
material (LD-CLSM)
Controlled low-strength material (CLSM) is a cementitious
material that is in a flowable state at the time of placement, and
that has a specified compressive strength of 1200 psi (8.3 MPa) or
less at the age of 28 days. This material is discussed further in
ACI 229R. Low-density CLSM (LDCLSM) meets this definition, and has
a cast density that is controllable from 20 to 50 lb/ft3
(320 to 800 kg/m3). The quantity of preformed foam in
the mixture determines the mixture's final density.
