Latent Hydraulic Effect of Ground Granulated Blast Furnace Slag on the Strength Development of Stabilized Peat

Peat is identified as soft organic soil with high water retention. It cannot be stabilized with Portland cement for soil improvement due to its impediment to cement hydrolysis. Hence, there is a need to explore suitable additives for effective peat stabilization. This study sampled tropical peat fro...
