VC delivered inaugural speech at the Seminar
The Seminar was inaugurated by the Vice Chancellor of Andhra University Prof. YC Simhadri was present as the Chief Guest, lit the light with a ‘Jyothi Prajvalan’ followed by a prayer. Giving the inaugural address, Prof. Simhadri reminded of the classical story of the Ramayana in which Lord Sri Ram who took the help of monkeys to build a bridge across the ocean in just six days time.

Durability is the need of hour – says Dr. Iqbal Ali
Dr. Iqbal Ali attended the Seminar as the Guest of Honor. He highlighted the need for more durable concrete and that IS 456 standard was an attempt to reflect this. He said that importance is gradually shifting from structural designing to more durable constructions. He said that today, Engineers have the flexibility of choosing from among various types of cements, mixtures etc. which was not possible a decade ago.
He said that a typical concrete technology is today displaying 10-year half life period and that its time to welcome new generation concrete mixtures such as Polymers, Polymer mixed concrete, self-stressing concrete, self-healing concrete, self-curing concrete, free fall concrete and self-compacting concrete.
Quality has to be looked after – says Sri Satyanarayan Singh
Sri Satyanarayan Singh gave the key note at the Seminar and stressed that Quality is a prime candidate in Concrete and Building technologies. He drew out examples from his career and said that Builders who are the real people who execute a project are the key people who can promise on quality of good or service. He said that a ‘Code of Conduct’ has to introduced and that Regulatory body should be set up by the State and Central Governments to look and implement Quality measures including Quality Check, Quality Assurance, Quality Control and Quality Assessment. He also said that Concrete mixtures have to be done by trained people and felt sad that even implementing Government projects, this was not looked at. Since Private Colleges may not enter into the scene, Universities can take up the change to provide testing mechanisms, design of better concrete products and offer such other consulting services. Quality should come at the minimum cost.
Book on Water Resources Engineering released
A book entitled “Book on Water Resources Engineering” authored by Sri Challa Satyanarayana Murthy was released by Sri Satyanarayan Singh. The Author was felicitated.
Felicitation of eminent personalities
Engineering Day Celebrations wont be of any good unless eminent Engineers were felicitated. Sri B Kantha Rao (Gayatri Vidya Parishad Engineering College), Janab MAR Ansari (Visakhapatnam Port Trust), Sri UAN Raju (M/s UAN Raju Constructions), Sri MRK Prasada Rao (M/s MVR & Sons), Prof. PSN Raju (Dept. of Civil Engineering, Andhra University) and others were felicitated.

Prof. PS Rao (Principal, Gayatri Vidya Parishad Engineering College) gave a technical talk on best practices on concrete mixing and other practices. He said that concrete pumping has to be used rather than on-site mixing of concrete.
Prof. DL Narasimha Rao spoke on sustainable development and trends towards supplemented cements in which waste materials that come out of industries are used as cement-replacements such as in slag cement. He said that the Government of India has made it clear that CC roads were to be laid for major projects instead of the conventional black tar roads which require frequent maintenance.
Dr GVK Prasad (Andhra Cements) spoke on the need of usage of Slag cements and drew out examples from the Industry where it was used. He said that Visakhapatnam being near the Sea shore should use Blended cement. He said that the HiTech City in Hyderabad was constructed using 100% slag cement and that the Parliament House Extension project was also using the same.
Prof. DL Narasimha Rao (Dept. of Civil Engineering, Andhra University) gave a technical note on Cracking of Concrete – Reasons and Precautions to be taken. He said that Sulphates and Chlorides were the prime agents that accelerate cracking in constructions, Magnesium Sulphate being a prime candidate for this effect. He explained in detail about various types of crackings and how to avoid them. He also explained about the IS 456:2000 Standard and various points in it including the classification of environments, minimum and maximum covers, cements and water proportions to be used etc.

Between 1884-1908, he worked on several Water and Irrigation projects and was responsible for the design of automatic shutters which were used in popular bridges.
When Muri River floods filled Hyderabad, the Nizam Kings asked for the help of Visweshwaraya who accepted the job as the chief Engineer. His Master Plan was the idea behind the technique that avoids floods for Hyderabad even today.
