  With natural aggregate concrete, the basic features of recycled and coconut shell aggregate concrete are investigated. The current study's focus is the examination of recycled aggregate and coconut shell aggregate at 0%, 5%, 10%, 15%, and 20% partial replacement of coarse aggregate in the production of concrete. The goal of the inquiry is to compare the effects of varying quantities of waste aggregate on the characteristics of concrete. Recycled aggregate is a non-biodegradable substance. Thus, the use of this form of technology would limit the amount of waste that ends up in a landfill while also reducing the depletion of fresh raw resources. Coconut shell, a byproduct of agriculture, can also be utilised as aggregate to prevent environmental harm. The primary benefit of coconut shell aggregate is cost savings (up to 40%) owing to self-weight decrease.

In this study, core samples were taken from column or reinforced wall in order to make reinforcement or restoration. The effect of the element height and volume of voids of these samples to the compressive strength were investigated. C25 type ready to use concrete was used and a column without steel was produced. During the production process, 15 cm reference cube samples were taken from the fresh concrete. After 28 days, 8 cores from reference cubes and 128 samples from column were taken and their compressive strengths were determined. As a result, the average compressive strength of the reference core samples was 36.95 Mpa and according to the height compressive strengths of other samples was ranging between 37.3 and 43.0 Mpa. The ratio of the increasing of the compressive strength changes between 0.95 and 16.37% according to the reference sample. Based on the experimental results, fuzzy Logic method was used for modelling of the experimental results. The paper demonstrates that fu...
