| Summary: | Strength in concrete is the main concern in concrete technology and its
advancement. In the recent decades, durability had become a crucial aspect in concrete
especially it was exposed to Malaysian Atmosphere. Many development and techniques
were improvised to enhance concrete strength and durability. One of the methods to
gain both traits in concrete is by adding epoxy in the concrete mixture. In Malaysia, epoxy concrete is relatively new, and thus experimental investigations need to be
conducted to understand in depth how its responses under Malaysian conditions. A
study was conducted to investigate the durability and development of strength of epoxy
concrete under Malaysian Atmosphere. 6 series of samples were prepared with various
contents of epoxy concretes, 100×100×100 mm and 150×150×150 mm were casted by
using Sikadur-52 as the epoxy. Pure mortar acts as control sample. The concretes were
compared and tested with compressive strength test, weather effect tests, acid attack test
and permeability test to see development of strength of epoxy concrete. It was found
that the epoxy was effective in binding the aggregates and cement where the
development of strength was increased. The epoxy was able to increase the strength of
the concrete where the higher content of epoxy will return the strength much higher if
compared with lower content of epoxy and pure mortar. Also it was found out that
epoxy will give a lower permeability compared with the pure mortar. Changes in
dimensions and density were also affected in the acid resistance test. It can be
concluded that the effects on the epoxy concrete is influenced by the content of epoxy. |
