This paper presents the performance of the concrete included the bio sulfur derived from the landfill and additives. The bio sulfur was obtained from the landfill site and derived the various chemical process. The bio sulfur is the liquid type and the results of initial compression tests show that the bio sulfur itself is not good enough to generate the compressive strength. The additives which are paper ash and desulfurization gypsum added to support and increase the compressive strength of the bio sulfur concrete. The resistance of chemical and sodium ability of the bio sulfur and additive concrete were evaluated using SEM and EDS analysis. The structure of the bio sulfur and additive concrete shows the dense micro particle and hard enough to resist the chemical and sodium intrusion.
