The thixotropic properties of contemporary mortars allow the insertion of mortar in small vertical seams by using a mortar pump without the need for traditional formwork. In such a seam, a vertical mortar connection for the transfer of shear forces can be created by simply adding a profile to the mortar-to-concrete interfaces. In this way a...

A significant part of composite concrete viaducts was built in the 50s and 60s. This has led to an increasing need for the reassessment of the precast concrete beam bridges in the Netherlands. Many of those bridges are nowadays subjected to higher traffic loads and consequently, have a certain risk of not complying with the currently used design...

Typically precast girders are designed and utilized as simple supported members. Alternatively, the precast girders can be made continuous at the intermediate support using cast-in-place concrete topping. Once the girders are made continuous, time-dependent restraint moments will occur. The magnitude of the restraint moment is mainly affected by...

Precast concrete appears to be promising in dealing with delays in housing construction, yet long lead times are apparent in this industry. Lead time refers to the time that elapses between placing and receiving an order. The construction company Janssen de Jong recognizes the problem of sub-components’ long lead times in precast concrete house...

Our knowledge of precast concrete facades is becoming more relevant each day.<br/>Buildings with precast concrete façades are relatively new in relation to monument listing, due to architectural and constructive innovations being related to these façades. However, these buildings are also next in line for demolition due to their age and...

The Dutch precast concrete company Schokbeton started activities in the early 1930’s, introducing well compacted concrete elements some of them plain, others mimicking the colour, details, and surface finishes of natural stone. Being a modern, industrially produced material with a traditional stone imitating look, Schokbeton served both...

This research optimizes the environmental impact of a conventional building foundation in Northern Europe while considering the economic cost. The foundation is composed of piles and ground beams. Calculations are performed following relevant building Eurocodes and using life cycle assessment methodology. Concrete and steel accounted for the...

In this report, the applicability of Precast Concrete Sandwich panels (PCSPs) is analysed and improved. This is done by a multitude of methods: a literature study is performed, an advanced, non-linear Finite Element model and simple linear analytical model are developed, and calculations have been performed on a design-structure from Lievense |...

The production of double-curved precast concrete elements for cladding or shell structures requires expensive CNC (computer numerical control)-milled formwork. As an alternative method, the innovative flexible mould for economically efficient and sustainable production of such elements is discussed in this paper. This method comprises the use of...

After the Second World War there were serious shortages of building materials and trained personnel, the demand for housing was high and construction budgets were low. Together these factors created an environment for the large-scale development of non-traditional residential construction systems in the Netherlands. One of these was the NEMAVO...

The framework of the research presented in the paper is a project oriented to promote the use of construction and demolition waste (CDW) as a new resource for constructing sustainable and very low-energy buildings. Intensive research activities have been carried out in application of recycled concrete and recycled brick as a replacement of...

In the 1920s, the improved concrete technology and growing acceptance of concrete as an aesthetical material resulted in an increased application of coloured concrete. This includes the use of organic and inorganic pigments, ground natural stone, consciously chosen coarse aggregates, and also a new technique: metallisation. This rare, yet...

The production of precast, concrete elements with complex, double-curved geometry is expensive due to the high costcosts of the necessary moulds and the limited possibilities for mould reuse. Currently, CNC-milled foam moulds are the solution applied mostly in projects, offering good aesthetic performance, but also resulting in waste of material...

The production of architectural elements with complex geometry is challenging for concrete manufacturers. Computer-numerically-controlled (CNC) milled foam moulds have been applied frequently in the last decades, resulting in good aesthetical performance. However, still the costs are high and a large volume of waste is produced. This paper...

Free-form buildings tend to be expensive. By optimizing the production process, economical and well-performing precast concrete structures can be manufactured. In this paper, a method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single element. The...

The precast concrete sector is growing and to continue this growth it is necessary that new innovations, ideas, technologies etc. are developed to improve the functionality of precast concrete structures. Many applications can be found nowadays for all different kinds of precast concrete elements. One such application for example is precast...

In an earlier article (CPI issue of August 2011 [1]) a method was presented for producing precast curved panels with a thickness of a few centimeters using the 'flexible mould method'. This method is the central theme in the PhD study of the first author on the realization of freeform architecture in concrete. The concrete panels manufactured...

The construction of buildings with free-form concrete surfaces can be accompanied with relatively high costs due to the production of uniquely shaped curved concrete elements. Delft University of Technology researches a method to produce such elements in a cost-efficient way using a re-usable flexible mould. The method requires a flexible...
