Self-compacting lightweight concrete (SCLWC) is an innovative high performance concrete which uses palm oil clinker (POC), a waste by-product from the palm oil industry, as the lightweight aggregates.

A concrete masonry unit (CMU) is a standard size rectangular block used in building construction. Those that use cinders ( fly ash or bottom ash ) are called cinder blocks in the United States, breeze blocks ( breeze is a synonym of ash ) [1] in the United Kingdom, and hollow blocks in the Philippines.

Another solution is to radically reduce the weight of the embankment by the use of extremely light filling materials. This article describes a road embankment built in lightweight clinker and expanded polystyrene with a concrete layer for protection and pressure equalization.

Three types of mixes oil palm shell lightweight aggregate containing different content of palm oil clinker as sand replacement have been used in this experimental work. Three types of testing that are workability, compressive strength and dry density were investigated.

Portland cement clinker is made by heating a homogeneous mixture of raw materials in a rotary kiln at high temperature . The products of the chemical reaction aggregate together at their sintering temperature, about 1,450 °C (2,640 °F).

In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder.

Oil-palm-boiler clinker (OPBC) is an agricultural solid waste from the incineration process of solid wastes in palm oil industry. The OPBC that is highly porous and lightweight in nature is suitable to be used as a lightweight aggregate. This paper presents a method to produce high-strength lightweight aggregate concrete using OPBC.

The main characteristic of this lightweight aggregate is its high porosity which results in a low specific gravity [17]. vermiculite and clinker aggregate. Insufficient water can cause lack of cohesion between the particles and therefore. The lightweight aggregate can be natural aggregate such as pumice.

A lightweight inert material, such as foamed slag, vermiculite, clinker, and perlite, used in unreinforced concrete for making structures of low weight and high insulation. Aggregate of low-bulk specific gravity, such as expanded or sintered clay, foamed slag, fly ash, exfoliated vermiculite; used ...

(clinker) is transferred by conveyor into the clinker cooler where it is cooled by air, forming a porous material. After cooling, the lightweight aggregate is screened for size, crushed if necessary, stockpiled, and shipped. Figure 11.20-1 illustrates the lightweight aggregate manufacturing process.

Every years Malaysia produce 4.0 million ton oil palm shell and a huge amount of palm oil clinker as waste materials. Oil palm shell (OPS) and palm oil clinker (POC) both are reusable source of lightweight aggregate (LWA) from the agricultural waste in palm oil industries.

lightweight aggregates. In the second category of lightweight concrete, namely concrete with lightweight aggregates, the various brands were more dissimilar due to the different types of aggregates each used. The usual aggregates were wood fibres or expanded clay. Wood fibres were used by Durisol and Fixolite.

Self-compacting lightweight concrete (SCLWC) is an innovative high performance concrete which uses palm oil clinker (POC), a waste by-product from the palm oil industry, as the lightweight aggregates.

Types of concrete block: 'Dense', 'Lightweight', 'Aerated' Dense aggregate block. In use from the 1940s onwards, dense aggregate blocks are very much the work-horse of the construction industry. Their distinctive properties of durability and strength make them an ideal and cost-effect solution for all types of load-bearing walls.

LECA is a special type of light aggregates that has been pelletized and fired in a rotary kiln at a very high temperature.As it is fired, the organic compounds are burn off forcing the pellets to expand and become honeycombed while the outside surface of each granule melts and is sintered.

lightweight concrete 1. LIGHTWEIGHT CONCRETE 2. DEFINITION concrete which uses lightweight aggregates May consist of lightweight aggregates are used in ordinary concrete of coarse aggregate and sand, clay, foamed slag, clinker, crushed stone, aggregates of organic and inorganic.

Materials used include OPC Type I, 10 mm nominal size POC coarse aggregate and granite. The palm oil clinker pervious concrete (POCPC) mixes were developed with a fixed water-cement ratio of 0.3 ...

Jun 03, 2011· The usual mix is I part cement to 6 or 8 of aggregate by volume. Of the four lightweight aggregates noted, well burned furnace clinker produces the cheapest block which is about two-thirds the weight of a similar dense aggregate concrete block and is a considerably better thermal insulator.

lightweight concrete using lightweight aggregate. In this study, palm oil clinker (POC) is used to replace normal gravel as course aggregate in concrete. There are two types of mix designs in this project, which are the normal self-compacting concrete as the control mix and the POC mix with POC replacement for course aggregate.

Lightweight construction. Clinker Ply: Similar to trad' lapstrake/clinker but with joins between planks glued with epoxy rather than copper clench nailed. Requires expensive materials (ie high quality multi laminate plywood), high skills and extensive tools (ie. rebate planes etc). Not easy to repair.

Utilizing waste material in the construction industry is an effective way to protect the environment and minimize construction cost. In this paper, palm oil clinker (POC) aggregates were used as coarse and fine aggregate replacement in lightweight concrete production.

Blast furnace slag is allowed to slowly cool by ambient air, is processed through a screening and crushing plant and is processed into many sizes for use primarily as a construction aggregate. Common uses are as aggregates in ready-mix concrete, precast concrete, hot mix asphalt aggregate, septic drain fields and pipe backfill.

lightweight aggregates, 0.04-0.08% drying shrinkage. Consists only of well-burnt furnace residues which have been fused or sintered into lumps.

Three types of testing that are workability, compressive strength and dry density were investigated. The workability of high strength palm oil clinker lightweight aggregate concrete was indicated using slump flowability following the procedures in [10].

type of light weight aggrgates clinker. ... The type of lightweight aggregate and its volume fraction in a mix determine the density of lightweight concrete. Minimizing the density obviously requires a higher volume fraction, but this usually causes aggregates segregation in a conventional mixing process. This paper proposes a two-stage casting...

Obviously, weight gains vary widely from product to product but the potential of "green" uses for by-product and recycled materials have become a focus for this type of aggregate. Cellular or Aerated Concrete. This type of lightweight concrete is the result not just of the product, but also of the process.

In this cement type, clinker and pozzolanic material such as (volcanic ash, fly ash, etc.) are mixed in a definite proportion with Portland cement. The pozzolanic materials do not have any cementing qualities when used alone, but when mixed with Portland cement, they react with cement components and form compounds with cementing properties.
