In construction cement mortar is consumption is about 30% of the volume of masonry. The durability and strength of masonry depends upon the strength of mortar also. In masonry mortar is laid between the courses of bricks hence its good compressive strength is essential requirement. In this investigation the compressive strength of cement mortar is tested with Nano Aluminum oxide. The water cement ratio is taken 0.5 and cement sand ratio is taken 1:3 by weight. It is found that while Nano aluminum oxide added 0.5–2% of the weight of cement compressive strength increases up to 16%.

Compressive strength and tensile strength determination is essential for any engineering material used in construction work. In this experimental work tensile strength of mortar is determined with Nano ZnO. The water cement ratio is taken 0.5 and cement fine aggregate ratio is 1:3. It is found that while Nano zinc oxide added 0.5–2% strength increases at 0.5 and 1% at higher curing.

Cement mortar is unavoidable part of any construction. Strength and durability of mortar is necessary for long life of structure. At the time of preparation of mortar, various admixtures are added for enhancement of its various engineering properties. Addition of admixtures alters it workability, strength, etc. In this experimental study, it is observed that by adding some nano-materials, the flow value of the mortar decreases, but by increasing the content of the nanoparticles, workability increases slightly. Similarly by adding polymer PVA, the workability increases than the control mix, when content of polymer is 2% of cement. The workability of mortar increases with addition of nano and polymer when both are added.

Human comfort is the key factor in all kind of developments, for this natural resources are exploitation is being continued. Though energy production have increased tremendously, but population growth rate is more than the development rate. Hence there is always scarcity of the electricity, safe drinking water. Intelligent houses with smart traffic, smart irrigation can make smart city and provide some solutions for these problems. In these review paper solutions of some common society problems with sensor based automation in infrastructure has been discussed. Major areas of overview are intelligent buildings, smart ventilation of buildings, integration of solar panels with smart roof, smart traffics control, and smart irrigation system etc. These smart systems not only saving energy, and water but also reducing the cost hence desirable. Though this arrangement need so many sensors, control system, management system, computer internets network hence complicated but solving our problems smartly. The future time will be of smart infrastructure.
