advantages and disadvantages of coconut shell concrete

Advantages And Disadvantages Of Coconut Shell Concrete

compressive strength and durability of concrete …,this study aims to investigate the effects of partially replacing cement with coconut shell ash (csa) in its compressive strength, sorptivity, and rsa. csa in this study was classified as a class n pozzolan, a cementitious material that makes a cheaper substitute for ordinary portland cement (opc)..use of coconut shell ash as aggregates,coconut shell may present itself as a potential material in the field of construction industries. the coconut shell is compatible with cement and no need to pre-treatment for using it as coarse aggregate. because of the smooth surface on one side of the shells concrete made with coconut shell presents better workability. coconut shell concrete shows good impact resistance. as compared to.

    Advantages And Disadvantages Of Concrete - Civil Engineering

    concrete can be manufactured to the desired strength with an economy. the durability of concrete is very high. it can be cast to any desired shape. the casting of concrete can be done in the working site which makes it economical. the maintenance cost of concrete is almost negligible. the deterioration of concrete is not appreciable with age.



    the addition of coconut-fibres significantly improved many of the engineering properties of the concrete, notably torsion, toughness and tensile strength. the ability to resist cracking and spalling were also enhanced. however, the addition of fibres adversely affected the compressive strength.



    however, there are advantages and disadvantages associated with this material. for example, while concrete becomes stronger and more durable with time, it is susceptible to water and freezing temperatures, meaning that water can seep into cracks and cause damage to the concrete.
