  • BIOMASS AGGREGATE CONCRETE FOR SOFT SOIL SUBBASE (S3) SYSTEM YL Lee, PhD, MCSM ashmann@gmail.comFaculty of Civil and Environmental Engineering, UTHM, 86400 Parit Raja, Batu Pahat, Johor Darul Takzim, Malaysia. 30 January 2013
  • Objectives:• To inspire innovation• To explore opportunities inresearch & postgraduate studies
  • Outline• Biomass aggregate concrete• Foundation on soft soil• Opportunities• Challenges
  • Rice husk ash (biomass aggregate)
  • Milestone achievement for the exploitation of solid wastes in construction
  • • Fact Sheet• Name of Rice Miller - Lok Eak Khim Rice Mill, Skun, Kampong Cham, Kingdom of Cambodia• Date of Installation – November 2007• Capacity of Gasifier – 250kW• Type of Gasifier – Downdraft type• Saving of Diesel to existing Diesel Engine – 85%• Carbon credit – not pursued• Addition of Gas Engine 250kW, installed in May 2008.
  • Biomass Silica Project in Cambodia
  • Bulk handling of biomass silica
  • Bulk handling of biomass silica
  • Prepacked biomass silica
  • Emerging Technology A method of using air bubbles and catalyst in cement mortar Reduce density Enhance durability performance On-site production of KUIKcrete
  • Research opportunities KUIK Block for soft soil subbase (S3) system
  • Test site at RECESS, UTHM
  • Soft soil subbase (S3) system
  • Soft soil subbase (S3) system
  • Novel combination of foamed aggregate and scrap tyres
  • S3 experimentation
  • S3 subgrade ready for pervious concrete pavement
  • KUiK block for pervious pavement
  • Biomass aggregate for plantation road
  • Technology Showcase Within 3 days, 1800m3 of foamed concrete (6m high) was cast. The total volume was about 180 units of low cost houses.
  • Density monitoring of foamed concrete
  • Stress Distribution due to Lifting
  • KUiK wall at UTHM
  • KUiK Cabin for construction research
  • KUiK Drain experimentation
  • The soft soil sample
