“…From a laboratory test result that has been reported by Naik et al [13] that used four different mixture:SC1, control mixture without fly ash while other mixtures SC2, SC3, and SC4 contained Class C fly ash at 35%, 45%, and 55% of replacement by mass. The results obtained shows that the use of high-volumes of Class C fly ash replacement in SCC significantly reduces the requirements of super plasticizer as well as the viscosity-modifying agent.…”

Abstract. Over the centuries, concrete is commonly been used in construction world due to its properties. From the conventional concrete until the concrete that has been diversify with innovations, the usefulness is still the same, which is as building materials. One of the innovations called Self-Compaction Concrete (SCC). SCC is a type of concrete that does not require any mechanical compaction at all. This type of concrete will leveled and compacted under its selfweight. Such concrete will accelerate the placement, reduce the labor requirements needed for consolidation, finishing and eliminate environmental pollution. In terms of sustainability, previous researchers have recycled so many waste in SCC for example coal ash, silica fume, hydraulic lime, rice husk ash and fine limestone powder. Recently, recycling fly ash and bottom ash in SCC has grasped the attention of researchers as it demonstrated promising results. Furthermore, previous investigations already confirmed the potential of fly ash and bottom ash in replacing aggregates in SCC represents a better option than landfill and at the same time will decrease pollution problem especially in coal combustion area. This paper reviews the fly ash and bottom ash replacement in SCC.

“…Since high-strength concrete (higher than 40 MPa at the 28-day age [4]) is now generally readily obtainable, the application of HSC as a viable construction material is now well accepted. However, if HSC is to be the construction material for use in any condition, then other properties must also be achieved in addition to the strength [5]. Some of these properties include, but are not limited to, the following: resistance to expansion caused by sulfate and alkali-silica reaction, low permeability to air and water, resistance to cycles of freezing and thawing, as well as chloride-ion penetration.…”

“…But, based on the experience with ordinary concrete, one can assume that HPC is more durable than ordinary concrete. Indeed, the experience gained with ordinary concrete has shown that concrete durability is governed by concrete permeability and the harshness of the environment [5,10].…”

“…The aggressive agents include gases (CO 2 , SO x , and NO x ) and liquids (acid rain, salt-bearing water, sea water, sulfate-bearing water, snow and ice water, and river or lake owing water). The primary variables in uencing concrete permeability are water to cementitious materials ratio, quantities of supplementary cementitious materials, grading and size of aggregates, compaction of concrete, and curing [5,11].…”

Abstract. This paper describes the e ects of variable curing temperatures on compressive strength and sulfate resistance of high-strength, high-performance concrete. Two di erent concrete mixtures were proportioned to attain the 56-day compressive strength of about 70 MPa upon moist-curing. One mixture contained more quantity of ASTM Class C y ash than the other one. For each mixture, one set of specimens was cured in a standard moist-curing room at 23 C and 100% relative humidity; another set of specimens was sealed in plastic bags and cured in an elevated, Variable-Temperature Curing Environment (VTCE). The average temperature of the VTCE oscillated between about 30 C and 41 C once per day. This study revealed that the VTCE-cured concrete did not signi cantly exhibit di erent compressive strength or ability to resist sulfates attack compared to the standard moist-cured specimens. Thus, it was concluded, based on the results of this research, that additional e ort to stabilize higher curing-temperatures would be necessary for eld-cured concrete.

“…One way of achieving stability of mix is providing higher amount of binder material which is classified as powder type and other way is using chemical additives like viscosity modifying agent (VMA) which is classified as VMA type self-compacting concrete. To increase the quantity of binder material, it is added with filler material like fly ash, blast furnace slag, lime stone powder and silica fume [1] [2].…”

Self-compacting concrete (SCC) is flowing in nature and hence viscosity modified agent (VMA) or higher amount of binder is used for stability of mix. The mix proportion of SCC is also different from normal vibrated concrete (NC). This modifies the properties of concrete at fresh as well as at hardened state. Three mixes, one VMA type SCC, one powder type SCC and one NC, are considered with identical water to binder ratio. Properties at fresh state such as workability and segregation resistance and at hardened stage such as compressive strength, elastic modulus, shrinkage, creep and elastic shortening are determined and compared. Powder type SCC shows superior properties at fresh stage. Also compressive strength of powder type SCC is found better than that of VMA SCC and NC. Observations show more shrinkage, elastic shortening and creep for powder type SCC as compared with VMA SCC and NC.
