|Abstract: ||.A:BsrRACJr ==========
. The e:x:periments were conducted to study ihe feasibility of
producing sandjlaper using locally available raw materials,' such as
mixture of broken bottles and laterites; starch as adhesive, charcoal
as bacikground and papers and fabrics materials as substrates.
From the results of sieve analysis, the following particle
sizes were obtained i.e 06.}t1m172l~ )1m, 30gUm and 421lm and only 300Nm
and 425jfm, were used for gt'ading while others were disc~ed.
Notable among the analysis carried. out was the test for the
strength of adh:.esive and its effectiveness when used as bin.der.
ever, the major analytical work was on testing the performance of
sandpS1?er and its effectiveness and as *ell comparing it wi th this
commercial type of sandps,per:respecrt1vely. Therefore, at the end of
this fMrVey, it was found out thatr the sandpa.per produced using local ,; ,.
raw materials can perform equally well ~ th the commercial end type when

represented on a histograph shoWing the area of the work pieces covered
as it increase progressively :for a particular sandpaper used, and this
was done both for paper and fabric materials respectively.
Finally, it was also discovered that, .the mo~e viSCOUS; fue
adhesive solution, the stronger its binding strength. However, from , . . . < .
Viscosi 1'\1 determination; it was found that at a temperatUre of 27 ·c,
and density of O.99g/iin3 the viscosity of the adhesiveS)lution is
