Abstract

Charcoal is one type of material that is quite potential in its use in the field of engineering and construction. Charcoal materials have several types of allotropes (different forms of charcoal material chemical structure) (Rampe 2015). The nature of the charcoal is very dependent on the raw material from which the charcoal material was obtained, in addition to the method and conditions of production. Charcoal material properties are very important in a variety of uses, especially as adsorbents, catalyst carriers, molecular sieves, electrode materials and so on. Another most important impact is if too much volume of fitration loss to the formation, the additives that exist in the cement will be wasted, it will also have an impact on the cost of drilling increasingly expensive, Filtration loss on the allowed primary cementing is 150-250 cc per 30 minutes. Whereas the squeeze cementing is 55 - 65 cc per 30 minutes. To determine the effect of adding additive Corn Charcoal Charcoal tested with a concentration of 0%, 1%, 2.5%, 3%, 3.5% filtration loss testing using the Filter Press LPLT (Low Pressure Low Temperature). And for free water is determined by using a measuring cup filled with a suspension of cement as much as 250 ml. Leave for 2 hours until free water occurs on the top of the measuring cup. From the filtration loss test with additive Corn Charcoal, the results are said to be feasible namely at 1%, 2.5%, 3%, and 3.5% it can reduce filtration loss. However, according to the statement above only the addition of CMC additives at concentrations of 1%, 2.5% and 3% are permitted in the filtration loss because it is below 250 cc. Free water testing with the addition of Corn Charcoal Charcoal with concentrations used in this study are, 1%, 2.5%, 3%, 3.5%. Judging from the results that have been there that each addition of Corn Starch Charcoal additives can reduce the occurrence of separating filtrate or called free water.
