This thesis presents a study on the use of fine crushed aggregates as replacement of natural sand in cement mortar and concrete. Material characterisation of three different types of fine crushed aggregates and their effects on the engineering properties of fresh and hardened mortar and concrete specimens were studied. Use of the fine crushed aggregates up to 40% to 60% can be considered ...
tion of Fly Ash, Ground Granulated Blastfurnace Slag, soil, and Quarry Dust (:::) are prepared and tested after 7 and 28 days. The dosages of coir fiber are selected as 1% of the brick weight and alkaline solution of 10 Molarities. The mix gives enhancement of compressive and flexural strength of MPa and MPa. The mixed formulations give better resistance against acidic ...

Abstract— Scarcity of river sand is one of the major problems in the construction industry. Studies were conducted to find out the feasibility of using .
Abstract This paper presents the effect ultrafine fly ash (UFFA) on compressive strength development of mortars containing high volume class F fly ash as partial replacement of cement. The experimental works are divided into two parts. Part one is conducted in binary blended cement mortar where Portland cement (PC) type I is replaced by UFFA at level of 5%, 8%, 10%, 12% and 15% (by wt).

The effect of molarity of alkali activator, manufactured sand (Msand), and quarry dust (QD) on the compressive strength of palm oil fuel ash (POFA) and fly ash (FA) based geopolymer mortar was investigated and reported. The variable investigated includes the quantities of replacement levels of Msand, QD, and conventional mining sand (Nsand) in two concentrated alkaline solutions; the ...
Fly ash reduces the amount of Portland cement and free lime as well as chemically binding up a portion of the free lime and salts that cause efflorescence. In addition, fly ash requires less water again resulting in a denser paste which aids in keeping moisture from traveling up from the bottom and from the top down. Water reducers of course, are also helpful at minimizing the amount of water ...
