The pozzolanic reaction happens between silica fume in addition to the CH making additional CSH in lots of the voids around hydrated cement particles This additional CSH supplies the concrete jointly with not only enriched compressive flexural and bond- power but also a heftier matrix
The fine silica sand is suitable for the flexible concrete which is used in the water treatment plant but if it is not available the normal sand can be used but it may effects the strength and flexibility of concrete We can also add fly ash silica fume blast furnace slag can also be used in the concrete
Silica Fume: Also referred to as microsilica this byproduct material is used as a pozzolan and is manufactured from the reduction of high purity quartz with coal in an electric arc furnace Silica fume can also be provided in a liquid form and is an extremely fine material Appropriate safety precautions must be employed when using silica fume
13-12-2001Silica is one of the most abundant oxides in the earths crust It exists in 3 crystalline forms as well as amorphous forms It hasmany useful properties and is used in a range of applications such as silicon elctronics refractories sand glass making building materials investment casting etc
To make silica fume concrete the concrete type and use shall be determined first The amount of silica fume added to different types of concrete is different Generally speaking the content of silica fume is 5-10% of the amount of cementing material When making silica fume concrete generally speaking the ratio of silica fume to cement is:
Glass powder is known as a reactive material with silica content more than 72% and potentially considered as pozzolanic material Moreover it is known that binder containing silica fume 10-26% by weight increases the compressive strength of concrete A low water to binder ratio is needed to increase the strength In this paper materials for
