To study the effect of condensed silica fumes addition on high strength mascrete concrete grade 60 in terms of compressive strength and durability / Roslan Majid
The main objective of this project is lo study the water absorptivity and strength characteristics of High Strength Concrete of grade 60 incorporating blended cement (Mascrete ) and Condensed Silica Fumes (CSF) added at 4%,8%, 12%, 16% and 20% to weight of mascrete. The strength development test are...

| Summary: | The main objective of this project is lo study the water absorptivity and strength characteristics of High Strength Concrete of grade 60 incorporating blended cement (Mascrete ) and Condensed Silica Fumes (CSF) added at 4%,8%, 12%, 16% and 20% to weight of mascrete. The strength development test are carried out at 1,3,7,28, and 60 days whilst the durability test at 28 and 60 days. The strength development test are done on 100mm cube while permeation tests are done on 150mm cubes respectively. Initial Surface Absorption Test (ISAT) apparatus is used to measure the water absorption of the concrete surface. Water curing at a temperature of 23 "C is employed for all specimens. From this limited study, it was found that: • dosage of CSF addition has a significant influence in mascrete concrete strength and permeation development. • higher dosage of CSF causes retarding effect on the mascrete concrete strength and permeation development. • dosage of PFA replacement has a significant influence in OPC concrete strength and permeation development |
