Abstract

This study aims to analyze the effect of adding Maxx 210 on the compressive strength and water absorption of lightweight concrete blocks. The research method used was a laboratory experiment with variations of Maxx 210 dosage of 0%, 5%, 10%, and 15% of the cement weight. A total of 40 cube specimens measuring 5×5×5 cm were tested at the age of 28 days. The results showed that the addition of Maxx 210 increased the compressive strength of lightweight blocks, with the optimum value obtained at the 10% variation of 4.12 MPa, which met the requirements of SNI 8640:2018 for structural lightweight blocks. Furthermore, water absorption decreased with increasing Maxx 210 dosage, with the lowest value of 10.95% at the 15% variation, which is well below the maximum limit of 25% as specified in SNI. A comparison with commercial lightweight blocks (Facon Interlite) indicated that lightweight blocks with the addition of Maxx 210, particularly at 10%, had better quality. Therefore, Maxx 210 can be recommended as an admixture in lightweight block production to improve both mechanical strength and material durability.
