Safe work with precast concrete | WorkSafe

Precast concrete is widely used in the New Zealand construction industry. Handling, transporting and erecting precast concrete elements are high-risk activities that have resulted in deaths and serious injuries to New Zealand workers. Every person working with precast concrete has health and safety duties.

Seven Year Performance of the City of Shoreview's Pervious

pavements in 2009. Pervious concrete pavements exhibit high hydraulic conductivity and high sound absorption coefficient in local or low-volume roads. They also provide cost savings through the minimization of hydraulic structures. The pervious concrete was designed for an anticipated 23% porosity and zero-slump. The design included a 7-inch

Forecast flexural strength of pervious concrete by SVR

Jan 01,  · Pervious concrete is a special concrete, vastly using in a road framework in recent times. Pervious concrete is produced by using coarse aggregate, water, and cement with slight amount or no fine aggregate. The principal purpose of using this type of concrete lies in its structural formation.

All four pervious concrete mixtures had acceptable workability. The unit weight of the fresh pervious concrete mixtures ranged from 115.9 lb/yd3 3to 119.6 lb/yd , while the 28 day compressive strength of the pervious concrete mixes ranged from 1858 psi (mix with 15% slag) to 2285 psi (pure cement mix).

PDF Mixing and Transporting Concrete

However, if the goal is stiffer concrete, a longer mixing time is required. 3.0 Transporting Concrete Transporting the concrete mix is defined as the transferring of concrete from the mixing plant to the construction site. Keep in mind that not all concrete is mixed on the actual construction site and could require some significant travel.

Lifting loops for transporting and handling of concrete

Lifting loops for transporting. Lifting loops are always used together with the lifting sockets for transporting and handling of concrete precast elements. Lifting loops are used for diagonal pull up to 45 degrees. There are many different types, sizes and loads. Lifting loops are not convenient for tilting of concrete elements.
