We go beyond the traditional concrete testing to determine condition of concrete and related construction materials. Experience matters.
Compressive Strength (ASTM C39) Concrete Testing
C3S performs compressive strength concrete testing utilizing the procedure set forth by ASTM C42 โ Standard Test Method for Obtaining and Testing Drilled Cores and Sawed Beams of Concrete. This concrete testing is performed to determine if it is high-strength concrete and meets the required compressive strength specified in the construction documents.

Los Angeles Abrasion Test for Aggregates
C3S performs this cement testing utilizing the procedure set forth by ASTM C 131 โ Test Method for Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine.
This concrete testing method is used as an indicator of the relative quality or competence of a source of aggregate. Particularly, it is effective in identifying aggregates with inherent cracks in them and the likelihood of sections of the aggregate breaking off/chipping off and entrapping large cavities in the concrete. Perennial problems of concrete pavement using weathered river gravel is prevalent in our area of southeast Houston.
This test detects these types of aggregates.
Cementย Testing for Organic Impurities in Sand
We perform this concrete testing utilizing the procedure set forth by ASTM C 40 โ Test Method for Organic Impurities in Fine Aggregates for Concrete.
This test determines the presence of deleterious organic impurities in fine aggregates that have the potential of impairing the durability of the hardened concrete. Specifically, it is used in ensuring that the effectiveness of air entraining agent used to resist freeze-thaw action in cold climates is not compromised.

Permeability of Concrete
C3S performs a rapid chloride permeability test of concrete utilizing the procedure set forth by ASTM C 1202 โ Test Method for Electrical Indication of Concreteโs Ability to Resist Chloride Ion Penetration.
This concrete testing method is also often resorted to in the evaluation of historical structures. Data generated from the test, by way of coulombs of electrical charge passing through a specified sample size, can be used to determine the propensity the section of the structure will readily permit fluids containing deleterious materials to gain access into the structure.
Slag in Concrete
Using slag in concrete can improve durability and reduce permeability. At C3S, we test concrete containing slag to ensure it meets performance standards and contributes to the strength and longevity of the structure.

Water Soluble Chloride Content Test (ASTM C1218)
C3S performs this concrete testing utilizing the procedure set forth by ASTM C 1152 Test Method for Acid-Soluble Chloride in Concrete and Defective Mortar.
This concrete testing method determines the content of water-soluble chloride in new or existing cementitious mixtures. This test is used routinely in investigating the potential for corrosion of embedded rebars in concrete structures. Especially in the repair and rehabilitation of infrastructure where a portion of the structure is in the sea/a body of water or pavements that have been subjected to salt application for ice removal.
This concrete testing method is often resorted to in assisting to determine the point within concrete where the critical chloride content to cause corrosion of rebar occur. Samples of concrete taken with a rotary impact drill at successive one-half inch depths are taken to the level of the rebar. The chloride content is separately determined for each depth and a graph developed to give the chloride ion profile in the structure.

Importance of Corrosion Mapping
Ensures Structural Safety
Compressive strength testing verifies that concrete can support specified loads, ensuring the structure’s ability to withstand the demands of its intended use.
Prevents Corrosion and Enhances Durability
Permeability testing evaluates the concrete’s resistance to harmful elements like chloride ions, which can cause rebar corrosion and lead to structural damage.
Guarantees Material Quality
Tests for organic impurities in sand and water-soluble chlorides ensure that concrete does not contain materials that could impair its performance.
Non-Destructive Evaluation
Ultrasonic testing and rebar inspections allow for the assessment of concrete integrity without causing any damage. This non-destructive test of concrete is essential for ongoing maintenance and evaluation.
Supports Rehabilitation Efforts
Destructive tests provide valuable data for repair and rehabilitation projects, ensuring that existing structures are properly evaluated and strengthened.
