Dr. Fixit Institute of structural Protection & Rehabilitation provides a wide range of services associated with condition assessment of structures and chemical analysis of cementitious materials such as cement, mortar and concrete. Services range from structural integrity test to laboratory based evaluation of damaged concrete, cementitious materials and related products.

Dr. Fixit Institute of Structural Protection & Rehabilitation (DFI-SPR) of Pidilite Industries Limited, Mumbai is a not-for profit company registered under section 25 of the Indian Companies Act, 1956. It prides itself as a leading institute in the country not only for knowledge dissemination in water proofing, repair & rehabilitation but also for structural protection of built environment. It has become the most preferred service provider for structural audit, repair & remedial waterproofing due to its expert professional services. The institute's Advanced Diagnostic Laboratory is

equipped with state of art facilities such as Non-Destructive Tests, Concrete, Petrography and Chemical laboratories. All these testing facilities are being accredited by National Accreditation Board of Laboratories for testing and calibration (NABL) as per ISO/lEe: 17025:2005 guidelines.

Structures suffer, often simultaneously, from physical, chemical and mechanical attacks. There are many test methods to assess the quality and degradation of concrete structures. However the chemical analysis helps to understand the exact nature and type of chemical attack that takes place inside the concrete structure. This assists in understanding the cause of damage. Not only this, chemical analysis can indicate whether a member will deteriorate in the future or not. Using various chemical analysis techniques information on various the contaminants and deleterious materials in concrete can be obtained. The other objective of chemical analysis of mortar and concrete specimens is to determine the composition and proportions of their constituents. It can also be used to determine the condition and composition of historic structures.

The chemical laboratory offers the following
testing facilities:

• Chloride concentration
• Water soluble chloride ions by specific ion electrode
• Chloride profiling from extracted core samples
• Measuring the resistance of concrete for chloride
  penetration by Rapid Chloride Permeability test     (RCPT)
• Determination of sulphate content of concrete
• Measuring the depth of carbonation
• Measuring the pH of concrete
• Pozzolanlc activities of Slag, PPC & PSC cements
• Oxide analysis of cementitious materials
  (Soluble Silica, Alumina, Iron Oxide, Calcium Oxide,
   Magnesia)
• Insoluble residue, Sulphur calculated as S03' and
   Loss on ignition

The facilities mentioned are available for structural consultants, research scholars, concrete material testing laboratories, Ready Mixed Concrete (RMC) manufactures and construction agencies. These facilities will be helpful for quality control during construction of metros, bridges, roads, highways, pavements, dams and irrigation projects etc. It can be also be useful to study the deterioration of concrete during structural audit of buildings and infrastructure projects.
