What is the meaning of CLSM?

Controlled low strength material, abbreviated CLSM, also known as flowable fill, is a type of weak, runny concrete mix used in construction for non-structural purposes such as backfill or road bases.

What is CLSM in construction?

Controlled low-strength material (CLSM) is a self-compacted, cementitious material used primarily as a backfill in place of compacted fill.

What is Fillcrete?

FILLCRETE is a powder product of primarily spherical-shaped granules made from submicron amorphous sili- con, free of crystalline compounds and commonly known as “silica fume (microsilica).” FILLCRETE has a high specific surface area (15-20 m2/g), very high Pozzolana reactivity and excellent filling capacity.

What is CDF concrete?

1.01 DESCRIPTION Control Density Fill (CDF) is used as a low strength, self consolidating fill material for confined spaces which can be easily excavatable at a later time. CDF is characterized by a high maximum slump of 8 inches. CDF is not a structural concrete and should not be used in such applications.

How hard does flowable fill get?

This mixture is capable of filling all voids in irregular excavations and hard to reach places (such as under and around pipes), is self-leveling, and hardens in a matter of a few hours without the need for compaction in layers.

What is flowable concrete?

Flowable concrete, which is also sometimes referred to as flowable fill, is similar in nature to the composition of lean concrete. It can be used to quickly and easily fill cavities. Its low strength and self-leveling capabilities contain strength of between 30 and 150 lbs per square inch.

Is flowable fill permeable?

Permeability. In general applications, designing flowable fill mixtures to have a minimum permeability equal to that of a uniform fine sand (4.0 x 10-1 cm/sec) is recommended.

How much is flowable fill?

What is the cost of flowable fill?
