In today’s global markets and increasing emphasis on quality, need for laboratry data has increased many fold and top of that accuracy and reliability of data is an another concern.

Our construction material engineering and testing credentials speak for themselves. our professional engineers having vast experience and understanding of construction materials and construction practies our team of engineers and tecnicians help our clients anticipate and minimize potential issuse and delays.

Our Building Material Testing laboratories are equipped with the latest sophisticated testing equipments. our services include not only Building and Road material testing services as well as engineering observation, structural inspection etc.

STRC has experience in testing wide range of construction materials,including Cement,Concrete, Aggregates, Admixture, Flyash, Masonary, Tiles, Wood, Steel, Aluminium, Bircks, Query stones,WMM, GSB and many more.

Our team of consultants and technologists create customized testing programs to meet the demands of manufacturers having proprietory products. When taking a new or revised product to market having it validated by a reputable independent test Laboratory will likely increase its acceptance in the marketplace.

Rebound Hammer Test

Rebound Hammer Test is done to find out the compressive strength of concrete by using Rebound Hammer as per IS:13311 (Part 2) : 1992. The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes. When the plunger of the rebound hammer is pressed against the surface of the concrete, the pring-controlled mass rebounds and the extent of such a rebound depends upon the surface hardness of the concrete. The surface hardness and therefore the rebound is taken to be related to the compressive strength of the concrete. The rebound value is read from a graduated scale and is designated as the rebound number or rebound index. The compressive strength can be read directly from the graph provided on the body of the hammer.


Core Cutting Test on Concrete

This is a partially destructive test that is used to co-relate the various other properties of the concrete viz. UPV, electrical resistivity, rebound number etc. It is customary to take cores of 4 inch diameter for compressive strength determination.Concrete core drilling for strength determination is again dependent upon various factors for reliability. The conversion of concrete core (typically 3 or 4 inch diametercore) strength into 150 mm saturated cube strength depends upon :

  • effect of coring
  • shape factor
  • size effect
  • direction of coring w.r.t. placing of concrete
  • h/d ratio

With so many factors contributing to the final 150 mm saturated cube strength, the strength variation may be + / – 10% – 15%. However, it can be used to confirm the results of UPV differing largely in the values & also for co-relation. Hence the UPV & core results should be judiciously used, interpreted & co-related.

Fabric Testing

The tent used to be the home of choice among nomadic groups the world over. Two well known types include the conical teepee and the circular yurt. It has been revived as a major construction technique with the development of tensile architecture and synthetic fabrics. M read more

Mud & Clay Testing

The amount of each material used leads to different styles of buildings. The deciding factor is usually connected with the quality of the soil being used. Larger amounts of clay usually mean using the cob/adobe style, while low clay soil is usually associated with sod b read more

Rock Testing

Rock structures have existed for as long as history can recall. It is the longest lasting building material available, and is usually readily available. There are many types of rock through out the world all with differing attributes that make them better or worsefor pa read more

Thatch Testing

Thatch is one of the oldest of materials known; grass is a good insulator and easily harvested. Many African tribes have lived in homes made completely of grasses year round. In Europe, thatch roofs on homes were once prevalent but the material fell out of favour as ind read more

Brush Testing

Brush structures are built entirely from plant parts and are generally found in tropical and subtropical areas, such as rainforests, where very large leaves can be used in the building. Native Americans often built brush structures for resting and living in, too.These a read more

Glass Testing

Clear windows have been used since the invention of glass to cover small openings in a building. They provided humans with the ability to both let light into rooms while at the same time keeping inclement weather outside. Glass is generally made from mixtures of sand an read more

Ceramics Testing

Ceramics are such things as tiles, fixtures, etc. Ceramics are mostly used as fixtures or coverings in buildings. Ceramic floors, walls, counter-tops, even ceilings. Many countries use ceramic roofing tiles to cover many buildings. Ceramics used to be just a specialized read more

Plastic Testing
