Field and laboratory characterization of the albedo of asphalt and horizontal surfaces Open
The rise in temperature in urban areas compared to surrounding rural zones is a major concern for modern cities. Part of this phenomenon is attributed to the widespread use of modern construction materials with low albedo, particularly for…

Recycling or downcycling? The difference between raw and stabilised earth explained Open
The development of innovative earthen materials necessitates a thorough evaluation of their recyclability. Although stabilisation is often regarded as a barrier to the recyclability of earthen materials, this study investigates the feasibi…

Strategy for the Mix Design of Building Earthen Materials Made of Quarry By-Products Open
The use of quarry by-products can enable the commercialization of a clay building material (reconstituted earth) thanks to minimal valorized and perennial stocks of materials. This study shows that quarry by-products can be used to mix des…

Gravity induced flow to characterize rheological properties of printable cement-based materials Open
This paper presents testing methods based on the deformation and fracture of fresh cementitious materials only subjected to their own weight. These new methods are dedicated to the study of cementitious materials designed for 3D printing o…

Nailing of Layers: A Promising Way to Reinforce Concrete 3D Printing Structures Open
Today, the extrusion-based 3D printing of concrete is a potential breakthrough technology for the construction industry. It is expected that 3D printing will reduce the cost of construction of civil engineering structures (removal of formw…

Cast, compaction, vibro-compaction or extrusion: processing methods for optimizing the mechanical strength of raw earth-based materials Open
In the last few years, raw earth construction has recovered much consideration due to its low environmental impact, its local character and its recyclability. However the strength of this material is really fluctuating as a consequence of …

Addition of bio based reinforcement to improve workability, mechanical properties and water resistance of earth-based materials Open
Large amounts of natural materials are used all around the world to stabilize, to protect from water or to enhance mechanical properties of earth-based building materials. Of these materials are; alginate, tannins, oak seed extract, cellul…

Extrusion of cement-based materials - an overview Open
Extrusion is a process that consists in forcing a formable material to pass through a die having the cross-section of the part to be obtained. This way of processing is used with conventional and fibre-reinforced cement-based materials to …

Structuration of natural muds in a rheological point of view. Open
This paper discusses the filling of estuary problem which can be defined as the accumulation of fine materials that causes the invasion of muds all over the estuary and that has a direct effect on the fauna and flora in the river, fishing,…

Durability of Alkali-Resistant Glass Fibers Reinforced Cement Composite: Microstructural Observations of Degradation Open
Usually, glass fibers in concrete permit the increase of the flexural strength. But the fibers in contact with cement are quickly degraded by alkali reactions due to the presence of portlandite. This article presents the results of investi…
