Used Concrete Sound Wall

Concrete for precast sound wall units and foundations shall have a minimum 28 day compressive strength of 2 500 psi or as re quired by engineering.

Used concrete sound wall.

It is a widely accepted contention that a concrete masonry noise wall barrier is unattractive and therefore undesirable for residential or commercial uses. Highway walls are expensive running more than 2 million per linear mile for one side of the highway. Sound testing is a simple non destructive test typically accomplished with a hammer or steel rod. But even if new materials were developed in addition to the popular concrete sound walls are currently made of everything from masonry and steel to wood and plastic the question would remain.

Decorative sound barrier fence. A highway sound barrier is an exterior wall built alongside a roadway or highway that interrupts the flow of sound waves from one area to another. Two types of highway sound barriers are used. 10 used concrete jersey barrier.

Simply stated sound testing involves striking the concrete surface and interpreting the sound produced. Reflective walls of solid concrete that create a barrier and push sound away from homes or other areas being shielded. Product specifications dimensions 10 l x 24 w x 32 h 8 top weight approx 4 000 per barrier condition used. Decoupling comes in to create an air chamber or gap between walls.

With color additives or stains and textured form liners a precast wall can blend in with a city s architecture and local topography or stand out by capturing community s theme or identity. Stonetree fence walls are vertically cast ensuring that a decorative texture in a natural looking block stone brick or custom designed pattern is formed on both sides of the wall. Sound waves need a continuous medium for traveling and concrete provides that as they are joined to other walls and other noise entryways like doors and windows to keep the sound going. Used for commercial development and roadway expansion projects these commercial grade sound walls block out sight sound wind and intruders in quiet beauty.

Concrete jersey barriers used. As clearly defined by the federal highway administration a noise barrier can achieve a 5 db noise level reduction when it is tall enough to break the line of sight from the highway to the receiver such as a home or person. A reflective wall which is solid will break up sound waves and reflect the noise back to the source location. High grade used concrete jersey barrier no lifting holes or fork slots slot ends connecting plates included.

Concrete mix designs may. We often use sound testing to help determine the defective areas in the concrete walls. Precast concrete sound walls reduce the perceived noise by as much as half while absorptive treatments have been found to further reduce noise pollution. Entrained air content shall be between 5 and 7 or as required by engineering.
