Abstract :
Various studies and experiments in the field of concrete have been carried out as an effort to improve the quality of concrete, material technology and implementation techniques obtained from the results of these studies and experiments are intended to answer the increasingly high demands of the use of concrete and overcome the obstacles that often occur in the implementation of work. in the field. The use of added materials (admixture) can help solve this problem. ThepurposeofthisstudywastodeterminetheextentoftheinfluenceofHe additonsubstanceonthecompressivestrengthqualityofconcrete.Thecomposition of the addition of He additons of 50 cc, 100 cc, 150 cc, 200 cc, 250 cc and 300 cc of the weight of cement, and the cement water factor is determined the same forall variations of the mixture, namely 0.5. The samples used were cylindrical (? = 15; h = 30) and blocks (15 cm x 15 cm x 15 cm), the quality of the concrete planned was K-450. The number of samples is 7samples. From the research, it was found that the highest compressive strength of concrete at the age of 1 day of concrete / in stable conditions, the compressive strength of concrete was found in the concrete mixture with He 200 cc additon, whichwas78.40Kg/Cm2andthelowestconcretecompressivestrengthwasfound in the concrete mixture with additone. He 50 cc which is equal to 61.18 Kg / Cm2. And from the results of the concrete elastic modulus test, it was found that the elasticity value of concrete increased by 6.43% in the concrete mixture with the addition of He 250 ccadditon.
