An enhancement in epoxy composites properties has been achieved by filler materials.
Base material used for making specimen was Bisphenol A (Epoxy rein 35%wt) + Silica (65%wt) and hardener material was Acid Anhydrite I (28%wt) + Silica (72%).

Before 1990s, the self-built house in the village used the masonry, wood as the building materials.
Meanwhile, both the roof and wallboard used the lightweight materials, so the earthquake resistant behaviour was very good.
The infilled frame structures was compose of all sorts of sintered concrete block, light wall materials etc.
Because the structural measure of wall materials and beam and column were imperfection, the earthquake damage was serious.
