Both industry and academia are rapidly developing processes, materials, projects to explore the potential of extrusion-layering additive manufacturing cementitious generally known as 3D concrete printing (3DCP). Because lack supportive formwork makes objects prone failure during printing, a key aspect remains so-called 'buildability', qualitative descriptor indicate resistance against such failures. Obviously, material characteristics applied print mortar an important (although not sole)...
In this paper a more sustainable 3D printable concrete is developed by the replacement of natural aggregate in mix with recycled brick (RBA). An existing used as reference and adjusted replacing 64% its RBA. The potential for sustainability building sector automation well recycling construction demolition waste therefore addressed. To date no research exists on use printed concrete, which has particular relevance developing countries, where bricks remains popular option. Two different types...
The path to implementing successful, productive, and sustainable off-site 3D concrete printing building systems is unclear. To provide clarity, this paper aims determine targeted actions for stakeholders in the construction industry. A systematic literature review a bibliometric analysis are conducted identify driver-barriers of Off-site Construction (OSC) Concrete Printing (3DCP). Thirty-four stakeholder-linked determined divided into industry, organisational, project, system levels....
The research on emerging digital construction techniques, particularly the 3D concrete printing of cement-based materials, is imperative owing to several economic, environmental, and societal benefits it offers over conventional cast-in-place concrete. In this study, limestone calcined clay cement (LC3) was utilised for printed (3DPC) production towards sustainable composite infrastructure by replacing up 50% ordinary Portland (OPC) with (LC2). fresh, rheological, hardened mechanical...
Extrusion-based 3D printing of a two-part metakaolin-based geopolymer concrete has long setting time, which could lead to inadequate structural build-up. This research explores an experimental mix formulation for application with reasonable time by the inclusion slag in activated sodium trisilicate solution and hydroxide (NaOH). The parameters are aggregate binder ratio (A/B) 1.6, alkaline activator (AA/B) 0.73, 0.5% fibre content volume mix, 1% superplasticiser mass binder, viscosity...
Most 3D printable concrete (3DPC) mixtures currently found in literature and the construction industry contain a high volume of ordinary Portland cement (OPC) which contributes to 10% global CO2 emissions. In this study, fraction OPC 3DPC is significantly reduced by using fly ash (FA), silica fume (SF), slag (GGBS) metakaolin (MK60) as alternative binders increasing aggregate-to-binder mass ratio from 1.6 1.75. The experimental programme planned considering evaluation pumpability,...
Abstract Two of the main activities RILEM Technical Committee 208-HFC Subcommittee 2 were preparation and publication state-of-the-art report on durability strain hardening cement-based composites (SHCC), performance comparative laboratory testing SHCC. In this paper mechanical tests are reported, as performed in laboratories five participating institutions. The purpose was to investigate compare crack patterns terms widths spacing, subsequently make recommendations for a suitable test setup...
