Read up on how to spot the signs of sub-par concrete and what some of the quality tests are that are typically performed before the material is brought on site to ensure its integrity.Concrete ProblemsSpallingSpalling happens when water enters concrete and forces the surface to either peel, pop out or flake. It happens because of moisture and sometimes salt as well. Eventually, it can cause crumbling and eventual destruction of a structure.In general, spalling takes awhile to show up, and older homes are particularly vulnerable to spalling incidents in their basements. Usually, incidents of spalling are not necessarily attributed to the quality of materials from a concrete supplier, although excess water is sometimes a culprit.There are some things concrete suppliers can to to prevent spalling in the first place, including:Pouring adequate cover of the rebarPlacing joints at the correct locations and within the right distancesEnsuring the edges and corners have adequate concrete coverMaking sure the concrete is mixed correctly and in the right ratios of water, aggregate and cementPopoutsThese generally cone-shaped pits, sometimes found in concrete flatwork such as driveways or sidewalks, happen when a piece of the concrete has broken away due to internal pressure. This can occur when moisture gets into the concrete, freezes and then expands.Luckily, popouts do not decrease the lifespan of a concrete slab or basement \u2014 customers just find them aesthetically unpleasant.Tips for preventing popouts include using:Aggregates that meet standard specsCements that meet ASTM standardsAir-entrained concreteConcrete with the lowest water content possible for the applicationProper curing and sealing methodsConcrete Supplier Quality TestsTo ensure their concrete is of adequate quality, many concrete suppliers undergo a series of quality tests before it\u2019s used.Slump TestA concrete slump test measures the consistency of fresh concrete before it sets and hardens. It\u2019s usually placed in a metal cone that\u2019s open at both ends and has attached handles. It\u2019s filled with concrete in four stages, and the cone is lifted vertically upward. Finally, the concrete supplier measures the slump of the concrete from the top of the slumped concrete to the level of the top of the cone.Other Concrete TestsIn addition to the slump test, other concrete tests for quality and durability include:Water permeabilityCompressive strengthRapid chloride ion penetrationWater absorptionInitial surface absorptionQuality concrete suppliers should be performing these tests on the quality and durability of their product according to industry standards.Concrete Supplier in Flushing, NYAt Best Concrete Mix Corp., we provide professional concrete services for our customers, mainly government contracts and other large projects.
