Discovery of alternative to the pozzolanic materials generated from industrial wastes was needed because of its unavailability when the industries was shutdown permanently. This paper deals the optimization of calcined bentonite clay utilization in cement mortar using response surface methodology (RSM). The variables were taken as three levels of calcination temperature (room temperature, 700 0 C and 800 0 C) and seven levels of calcined bentonite (0%, 5%, 10%, 15%, 20%, 25% and 30%). The compressive strength, workability, strength activity index and sorpitivity were taken as responses. The fresh and hardened properties of all determined for all mixes. Design Expert 11.0 version was utilized to carried out modelling and optimization using RSM. Workability was decreased upon increasing the calcination temperature and bentonite content in cement mortar. This attributed to high water absorption capacity of bentonite. The peak compressive strength was displayed by 20% replaced bentonite calcined at 800 0 C cement mortar after 28 days curing. Strength activity was improved upon increasing the percentage of bentonite calcined at 800 0 C. The sorpitivity of cement mortar was improved by incorporation of bentonite calcined at 800 0 C. The generated models from RSM were significance in all the factors considered. Optimum performance of the responses was observed at 15.25 % bentonite substitution calcined at 800 0 C

Discovery of alternative to the pozzolanic materials generated from industrial wastes was needed because of its unavailability when the industries was shutdown permanently. Consumption of pozzolanic materials in concrete will be a safer solution for this problem. Numerous studies were presented for utilization of fly ash, Ground Granular Blast Furnace Slag (GGBS), Metakaolin and silica fume as a pozzolanic material in concrete. LC3 is a type of cement by mixing of limestone, calcined clay and gypsum, a few literatures were available on LC3. This paper presents the overview of research work presented on physical, chemical, performance in cement mortars like consistency, setting times & compressive strength, properties of fresh & hardened concrete like workability, compressive strength, split tensile strength, flexure strength made LC3.

This work discusses hybrid autonomous vehicles that are grounded and aerial vehicles that are utilized to select their course based on their environmental characteristics. It includes algorithms for path planning, obstacle avoidance, and trajectory planning. It also has a microcontroller, known as the PIXHAWK Flight Controller, for various transmissions and configurations. Calibration and testing are performed using Mission Planner software. This article shows the different problematic features of an autonomous vehicle with several functionalities.
