Microbiology induced cracks remediation technique is a method that has been proved beyond doubt of its efficiency. The review of literature carried out in this area indicates, that the work related to quantification of repair technique in comparison with conversional methods of repair is scarce. The investigation includes two different types of specimens namely cubes and damaged RC beams subjected to high temperature, that are already available. For the cube specimens two different water cement ratios (0.56) with normal, porous (no compaction) and cracked cubes are included. The cracking of cues is done in a pre determined way by inserting a 0.5mm thick aluminum plate to a depth of 75mm top on a 100mm size of concrete cube of m20 grade mix B. sphaericus is used for investigations. The investigation of damaged beams includes three different digress of damages namely, low medium, and high, determined by rebound hammer and Ultrasonic pulse velocity test. The comparison of results of cubes and rehabilitated beams lead to the conclusion, that the bio concrete application is the most effective one the cement mortar is the least effective method.- Utilisation of Fly Ash and Fibre in Concrete

Strength of fly ash concrete made with 10, 15, 20 % and fibre made with 0.1, 0.15, 0.20 % of cement replacement was evaluated in terms of its relation with compressive strength and workability test. Comparison was made between ordinary Portland cement and fly ash concrete and natural fibre. Test results indicated that strength of concrete having cement replacement up to 15% of fly ash and 0.15% of fibre was comparable to the normal concrete mix without fly ash and fibre. The results confirm that fly ash concrete and fibre concrete is a promising material for long term strength development. This was due to the fact that early age strength of fly ash and fibre concrete was lower as compared to strength of control concrete. From the viewpoint of sustainable development, it is a strongly viable solution as a building material in the years ahead.Keywords

Premna serratifolia (also known as Pachumullai) belongs to the family Verbenaceae, is a medicinal plant known as Agnimantha in Ayurveda. It has potential hepatoprotective and cytotoxic activity. There are many phytochemical and bioactive compounds present in the plant parts of Premna serratifolia. In addition to this, it has higher antioxidant and antimicrobial activity which is beneficial to human health as a therapeutic adjuvant. However, the nutritional components in P. serratifolia have not been probed, though it was consumed during special rituals. Further the anti-anemic effect of P. serratifolia was not yet studied. The present research aimed at assessing the micronutrients (Iron, Phosphorus, Calcium, Ascorbic acid) in P. serratifolia leaf, and the ethanolic extract of P. serratifolia leaf at two different dosage (100mg and 200mg) was examined for hematological parameters (Hemoglobin, Red Blood Cell count and Mean Corpuscular Hemoglobin) in anemic rats and the value added snacks like biscuit, vadam and murukku were formulated at two different ratios by using P. serratifolia leaf powder. The results showed that P. serratifolia leaf extract had higher impact on the hematological parameters when compared with standard drug ferrous fumarate and the higher incorporation of P. serratifolia leaf powder helped to increase the nutrient content in formulated snacks.
