The utilization of pulverized fuel ash (PFA) and palm oil fuel ash (POFA) in producing a new construction material is seen as one of the ways to reduce the quantity of these wastes or by-products disposed at landfills. These materials are identified as pozzolana which are used as a partial replacement of the Portland cement. This step enables building materials to be …

Following these findings, more researchers have integrated POFA as one ingredient in the mix to produce a new type of concrete [10-13]. POFA is a by-product produced in palm
In this project different combination of Fly Ash and Rice Husk Ash as a partial replacement of cement and river sand by quarry sand is carried out. The composition of 7.5% Rice Husk Ash + 22.5% Fly Ash with 60% of quarry sand gives maximum strength results. Keywords: Admixture, Cement, Fly Ash (FA), Quarry sand (QS), Rice Husk Ash (RHA).
Again, decrease in compressive strength has been observed if cement is replaced by more than 25% with quarry dust. In one more experimental study it has seen that rice husk which is also a waste material from rice mill, is added in form of ash with quarry dust as partial replacement to cement content. In this, rice husk ash is added in 5%, 10%

General use of the Portland cement, Siliceous (ASTM C618 Class F) Fly Ash, Calcareous (ASTM C618 Class C) Fly Ash, slag cement, and silica fume in concrete is as primary binder, cement replacement, cement replacement, cement replacement, and property enhancer, respectively . 2. Types of Cements and Their Composition and Uses
It may be used as a partial replacement for Portland cement in concrete, but follow these limits: 1. Do not replace the cement quantity more than 15 percent by weight. 2. Replace cement with fly ash at the rate of 1.25 to 2.0 lbs (1.25 to 2.0 kg) of fly ash to 1 lb (1.0 kg) of cement. 3.
Whereas replacement of cement Along with the utilization of rice husk ash by 5% of silica fume with a w/p ratio of as cement by replacing it with the cement 0.8 gave better compressive strength at the is additionally reviewed for analyzing the time period of 7 and 14 days, but it fails in strength characteristics of concrete.
The use of pozzolanas for making concrete is considered efficient, as it allows the reduction of the cement consumption while improving the strength and durability properties of the concrete.
