Engineering Properties of Interlocking Blocks with Coatings
Abstract
The main objective of this study is to compare interlocking blocks with different coatings on compressive
strength, water absorption, and durability. Interlocking blocks were modeled as samples with size 5x5x5 centimeter
by cement: lateritic soil ratio at 1:7. After 7-day curing, samples were coated with acrylic resin, silicone, and siloxane
coatings. Then compressive strength test, water absorption test, and durability test were performed. The results
show that all three coatings can reduce water absorption of samples. Siloxane coating gave the lowest water
absorption. In terms of compressive strength, all types of coatings gave no effect to compressive strength. In terms
of durability, the acrylic resin coating shows lowest weight loss due to wet and dry process.
