The The cement cement was mixed mixed using two two ladle ladle then the cemen cementt was putted putted in the vicat mould.
3.3) The cement surface was flatten once using the ladle. The 10mm diameter of plunger was degrading so that surface was touched before it’s free.

3.4) The amount amount of penetration penetration was was measured. measured. The penetration penetration process process was repeated repeated With the different different water label which 125ml, 130ml, 130ml, 135ml and so on until until the Consistent standard cement paste was yielded yielded when the vicat plunger was Penetrate at the 5mm from the base mould.
3.5) The graph graph of water water against against penetrati penetration on plunger plunger level from from the base of mould mould was plotted 3.6) Standard Standard consisten consistentt was defined as the the percentag percentagee of water which which can yield yield the cement paste with locality of plunger p lunger at 5mm from the vicat mould 3.7) The value of standard consistent , temperature and the air moisture while the experiment 3.8) The factors that influence the exactly result was discussed
