Building Materials
Today's competitive markets and increasing emphasis on quality place a heavy burden on both the
providers and users of laboratory data. Compliance with National and International standards is
essential for manufacturers and suppliers to maintain credibility with clients; what's more,
failure to comply with these standards can result in businesses being forced to close.
Spectro is one of the top ranking testing laboratories. Our construction materials engineering
and testing credentials speak for themselves. Our professional engineers having vast experience
and understanding of construction materials and construction practices. Our team of engineers
and engineering technicians help our clients anticipate and minimize potential issues and delays.
Our laboratories are equipped with the latest sophisticated testing equipments. Our services
include not only material testing services as well as engineering observations, structural
inspections, NDT inspection etc. We undertake analysis of the physical (durability, strength,
load, resistance) and chemical (composition) properties along with microstructural analysis.
We provide field testing services and laboratory assessments of all types of construction materials,
including aggregates, masonry, Admixture, asphalt, concrete, rocks/soils, Cement, Flyash, Tiles,
Wood and even steel.
Our major clients include DMRC, Airport Authority, DDA, EIL, Refineries, NTPC, NHPC, JP, Gammon etc.
The Rapid Chloride Permeability Test
Corrosion of reinforcing steel due to chloride ingress is one of the most common environmental
attacks that lead to the deterioration of concrete structures. Diffusion occurs when the concentration
of chloride on the outside of the concrete is greater than on the inside. This results in chloride
ions moving through the concrete to the level of the rebar. When this occurs in combination with
wetting and drying cycles and in the presence of oxygen, conditions are right for reinforcement
corrosion.
The rapid chloride permeability test is being used as a measure of the “permeability” of concrete
to chloride ions. The more proper term would be “chloride penetration”. Many highway agencies have
adopted the test and it was included in High performance bridge specification. We provide The Rapid
Chloride-ion Permeability Test (RCPT) facility. The test is simple to conduct and that can be
performed in a short time. Other Permeability tests take weeks or months to complete.
