About Me

I am Salla Sanjay R., a Quality Manager at International Cricket Stadium - Varanasi, Egis India Consulting Engineers Pvt. Ltd. (Egis Group), a leading global architecture, consulting, construction engineering, and operating firm. Egis Group works side-by-side with clients to build a more balanced, sustainable, and resilient world.
Previously, I worked at BVR STRUCTCARE Pvt. Ltd. as a Quality and Technical Manager. It is a certified ISO 9001: 2015 company that provides consultancy and testing of mechanical, chemical, and NDT construction materials. I have also been actively involved in proficiency testing activities and know about ISO 17025, ISO 17043, and ISO 13528.
I completed my doctoral research under the guidance of Dr. C D Modhera, Professor (HAG) in the Structural Engineering Division of the Department of Civil Engineering, S V National Institute of Technology – Surat, an Institute of National Importance under the Ministry of HRD, Government of India.
I completed my Bachelor of Engineering Degree in Civil Engineering from the Birla Vishvakarma Mahavidyalaya, V V Nagar - Anand Gujarat (Affiliated with Sardar Patel University); during my graduation, I worked as a trainee engineer on a construction site (2010 - 2012). Further, I completed a Master's Degree in Construction Engineering and Management from Birla Vishvakarma Mahavidyalaya, V V Nagar - Anand Gujarat (Affiliated with Gujarat Technological University). After completing my post-graduation studies, I started consultancy work (SparkJ Technical Consultancy) regarding quality control, and third-party inspection for ongoing projects. In addition to this consulting services for ISO 17025: 2017, ISO 17043: 2023, and BIS certification, laboratories can enhance their testing processes, improve the quality of their testing and calibration services, and ultimately demonstrate their competence and reliability to customers and stakeholders.
My research area is to study the effect on concrete's fresh, mechanical, and durability properties after utilizing different industrial wastes in the concrete. I am also working on the pozzolanic reactivity and the microstructural properties of cement and concrete composites made of other supplementary cementitious materials. In addition, I am also working on different research areas like multi-criteria decision-making techniques, energy impact analysis, life cycle analysis, and value engineering for sustainable development.
I am proficient in concrete and building materials. My profile demonstrates teaching, field, and research experience. I also worked on construction materials, concrete mix design, placement, and performance constraints. I cooperated with NABL-approved building material laboratories for staff training, report writing, SOP development, and quality manual preparation as per ISO/IES 17025 in the Gujarat Region.

AREA OF RESEARCH

The current era shows that innovation and reuse of industrial by-products are necessary to protect the environment and sustainable development. The production of cement highly harms the environment in terms of CO2 emissions. Cement production contributes nearer to 5.0% of global pollution, which induced CO2 emission. The present study shows the role of supplementary cementitious materials (SCMs) in construction industries. The use of two different SCMs, cinder and processed GGBS, was used to replace cement. In the present study, different blends were prepared by replacing ordinary Portland cement (OPC) with cinder up to 70% at the interval of 10% and up to 50% of processed GGBS with 5%. The different tests were conducted like specific gravity, setting time, fineness, and compressive strength of different prepared blends to ensure the pozzolanic reactivity of SCMs. X-Ray Florence test (XRF Test) results showed that available oxides like calcium, silica, aluminum, and iron oxides are suitable for replacing cement with cinder and processed GGBS. In addition to these, to find out possible optimum among the prepared various blend Techniques for order performance by similarity to ideal solution method was adopted. Cost analysis shows that the overall cost of material can be reduced by 16%. Energy analysis shows that cinder and processed GGBS could reduce energy consumption by 24.56% and 3.6%, respectively.
