Different Temperatures

The mechanical behaviour of carbon-black (CB)-filled rubber is temperature-dependent. It is assumed that temperature affects the fatigue life of rubber products by changing the tear energy of the material. The static tearing behaviour and fatigue crack propagation behavior of CB-filled rubber at different temperatures were investigated in this study. The critical tear energy of the material was measured through static tear fracture tests at different temperatures; it is shown that the critical tear energy decreases exponentially with increasing temperature. A fatigue crack growth test of a constrained precracked planar tension specimen was conducted at room temperature; the measurements verify that the fatigue crack growth follows a Paris–Erdogan power law. Considering the temperature dependence of the critical tear energy, the temperature dependent fatigue crack growth kinetics of CB-filled rubber was established, and the fatigue life of the material at high temperatures was predicted based on the kinetics. The predictions are in good agreement with experimental measurements.

Two Samples

Chlorine is used in several ways in industry. In such situations, where residual chlorine persists as pollutant, Activated carbons like animal charcoal, carbon black and coconut charcoal can serve as agents to remove residual pollutant “chlorine” by the process of adsorption. Five samples of Carbon black, six samples of active Carbons and two samples of charcoals were treated with a stream of chlorine @0.4 litre/hour at temperature varying from 300 to 1200 C. Chlorine is adsorbed partially physically and partially chemically. Percentage of the chemisorbed increases with rise in the temperature. Maximum percentages of chemisorptions occur at 1200 C while the maximum uptake, physical as well as chemical, takes place at 300 C, which was the lowest temperature. It is seen that activated carbon, carbon blacks and charcoal differ markedly by in their total chlorine uptake at 300 C. Activated carbons associated with high surface were seen to take up maximum chlorine. Fall in surface area is more in active carbons as compared to carbon black due to greater adsorption of chlorine. This probably shows that micro porous carbons are better adsorbent for chlorine adsorption. The unsaturated sites also play far dominant role and provide centres where the adsorption takes place predominantly. Uptake of chlorine is enhanced on evacuating the carbon samples at 6000 C and 10000 C. This is due to the creation of more unsaturated sites. Process of adsorption cum chemisorption takes place through different kinetic stages with different energetics. The activation energies keep on increasing with increasing amounts of chemisorption.

Smart Concrete

Smart concrete technology provides a new alternative way for health monitoring of reinforced concrete structures. In this paper, the piezoresistivity of two kinds of smart concrete filled with carbon black or carbon fiber was studied, and two types of embedded sensors were fabricated using the smart concrete with favorable piezoresistivity. The sensing performance, the measuring methods and the response to environmental temperature and humidity of embedded sensors were investigated. A compensation circuit was incorporated to reduce the effect of temperature and humidity on the output of embedded sensors. The sensors were embedded in concrete beams and columns to monitor the structural compressive strain under field conditions. Experimental results indicate that the embedded sensors fabricated using smart concrete filled with carbon black or carbon fiber feature favorable sensing performance (gauge factors are 55.28 and 138 respectively). The self-sensing concrete components embedded with these sensors can realize the monitoring of their local compressive strain. It therefore can be concluded that the prepared smart concrete and the developed embedded sensors have great potential to be used for health monitoring and damage assessment of concrete structures.
