DURABILITY IMPROVEMENT OF PRECAST CONCRETE PRODUCTS

Precast Concrete Elements

Lattice-girder floor slabs and double-wall elements have been successfully used in building and industrial construction for decades. These precast elements of 50 – 70 mm thickness serve as permanent formwork for the subsequently added in-situ concrete creating a monolithic structure. The high prefabrication level allows the construction period to be significantly minimized. The main goal is the...

Experimental Study on Durability Improvement of Fly Ash Concrete with Durability Improving Admixture

In order to improve the durability of fly ash concrete, a series of experimental studies are carried out, where durability improving admixture is used to reduce drying shrinkage and improve freezing-thawing resistance. The effects of durability improving admixture, air content, water-binder ratio, and fly ash replacement ratio on the performance of fly ash concrete are discussed in this paper. ...

Foam Concrete Precast Elements in Composite Concrete-GFRP Plate Girders

This paper is focused on using foam concrete as structural element in polymer-concrete composite plate girders. Trial mixes of foam concrete and different proportions of foam agent were considered to obtain the suitable mix that can be used as structural element in composite girders system. Details of the experimental investigations on foam concrete precast slabs and polymer-concrete composite ...

Simulation Modeling and Optimization of Stockyard Layouts for Precast Concrete Products

Stockyard is a hob of information that reflects the production, stock and sales of precast concrete products. The stockyard layout plays an important role in storage and retrieval of the products. Stockyard layout planning offers a complex task as large number of products are involved with different handling and storage requirements, and large stock is inevitable due to seasonality of demand. T...
