CHAPTER 3

EXPERIMENTAL INVESTIGATION 3.1 General
The raw materials required for paver block manufacturing are fly-ash (Fa), Quarry dust (Qd), Stone aggregates, Cement (OPC) and Water.

3.2 Material Used
In this study, ordinary Portland cement ASTM type I and water of drinking quality were used. Fly ash used in this paper, produced from ignite coal, was obtained from the Thermal Power plant in Paricha, Jhansi (India) Interestingly, it has the total sum of SiO2, Al2O3, and Fe2O3 at ≈69% with quite a high CaO content (≈20%). Thus, the fly ash used in this study will be defined as high-calcium fly ash. Finely ground limestone powder was supplied from Ashutosh Chemicals ,Talik Bazar Chowk Near Old Delhi Railway Station.

3.3 Test on materials

1. The Cement were tested for physical properties such as: Fineness test Standard consistency test Soundness test Setting time test Specific gravity test,
2. The Aggregates were tested for physical properties such as: Particle size analysis test Specific gravity test Water absorption test Abrasion value,
3. The Stone dust were tested for

A sample of 400 gm. of cement was taken and a paste with weighed% of water was prepared for the trial. The paste was prepared in standard manner and filled into the vicat mould within 3-5 min. after completely filling the mould was sharked to expel out air. A standard plunger of 10mm dia. And 50mm length is attached to vicat apparatus and brought down to touch top surface of cement paste in test block and quickly released allowing it to sink in to paste under its own weight. Take the quantity of it by nothing the depth of penetration of plunger. This procedure is repeated till the plunger penetration will be 33-35mm from the
