Analysis Effect of Adding Sodium Lignosulfonate / black liquor on the Compressive Strength of Concrete

Abstract

Compound of Natrium lignosulfonat representing result from other side the process of pulp can be exploited
to various need, like surfaktan (dispersan, emulsifier), fastener (binder of agent), fixative, mixturer of
livestock food, ion exchanger resin, additive materials in cosmetic industry, elementary materials and
pharmacy of making of lignine of vanilin. In its application, lignosulfonat natrium can be used as by fixative
(binder of agent) and lasing of concrete mixture able to add strength fasten between particle effect of nature
of adhesive and also pursue diffusion irrigate in material effect of nature of its its[his] hence pore at concrete
become smaller because have been filled by liquor black so that concrete [do] not is easy to penetrated by
water compared to normal concrete (without there is mixture) which is its big pores, peculiarly addition of
application liquor black at building construction which is dampness memilki and high sour content because
can make brittlely of iron bone frame and concrete or existing concrete in building construction. Strength
depress which is is maximum to be determined by composition of black liquor at informing against making
of concrete by comparing of condition of normal concrete. Of this research is got by optimum condition at
addition 3,5 % black liquor / Natrium lignosulfonat obtained by strength depress 395,45 KN / cm2 .
Research having taken steps, lignosulfonat natrium can be used as of additive lasing of and concrete of
water admixture reducing.
