Concrete Hollow Blocks from Waste Coconut Shells

Did you ever wonder staring at your walls at home and wonder the corners of it, if how the concrete blocks give a constant foundation in it?

This study will give you insights on how to produce the concrete blocks by generating product using agricultural waste as well develop an alternative construction material that will lessen the social and environmental issues. It  also  covered  the  way  to  the  recognition  of  using  coconut  shells  and  fiber  as  substitute  for  aggregates  in developing  concrete  hollow  blocks.  Our environment is facing issues concerning the production of materials so instead of stick to the usual requirements, this solutions may be useful to improve the situation of our environment, by using recycled materials from waste coconut shells. Substituting waste materials in construction is well known for conservation of dwindling resources and preventing environmental and ecological damages caused by quarrying and depletion of raw materials.

The waste coconut shells have the technical specifications components that concrete hollow blocks have through the mechanical properties of compressive strength, modulus of elasticity, modulus of rapture, absorption, thermal conductivity, and fire resistance. The good indicators of coconut shell and fiber as aggregate are; particles shape and affects work ability of fresh texture, resistance to aggregate is low in crushing value, this will not give high crushing, absorption affects the mix proportions and control water content to maintain surface moisture water-cement ratio, grading economizes cement content and improves work ability, resistance to where frost action deteriorates freezing and heating.And lastly, the lightweight reduce weight of structure.

Our modern construction technologies are being developed, to respond to ecological   and   social issues of excessive use of raw materials from nature. The main objective of this study will give partial re-placement  for  the  aggregates and  will  determined the  ability and  benefits to  the  concrete hollow block. The simple concrete block will continue to evolve  as architects and block manufacturers  develop  new  shapes  and  sizes.

The researcher develops this experiment through collecting coconut shells and fiber. If gathered materials are wet, it will undergo drying process, or if dry it will be directly screened to discard foreign materials. Shells are crushed and fibers are stripped from coconut husk, after crushing and stripping it will be screened again to discard foreign materials. Physical property is observed through sieve analysis, if it will confirm with the standards. Concrete hollow block sample is done by mixing crushed coconut shell and fiber, sand and cement. Mixture is poured to the machine to form a 4 inches concrete hollow blocks. The next stage is curing the specimen for 7, 14 and 28 days on the said dates the specimen will undergo laboratory test such as compressive strength test, moisture content, and absorption.

In fact we can escape the crisis. We can return to the community of life, we can re-situate ourselves, in thought and experience, within and not against the more-than-human world. But we will not do so if we continue to suppose that we face only a practical problem: how to recycle better or pollute less or save the forests…all of this is crucial too…the environmental crisis ultimately lies deeper, challenges us more profoundly, more philosophically and offers us unsuspected and fabulous opportunities.
