In this comprehensive guide to binders for Binder Jetting, we have explored the essential role of binders in the 3D process, discussed the different types of binders available, including water-based, organic/inorganic, reactive, and hybrid binders, and examined their advantages, disadvantages, and applications.
Abstract: A binder for refractory castables is a bonding material that bonds a loose powdery mix, retains its shape after casting and allows the cast shape to set and harden for handling and further processing. A binder also improves sintering, as the castables are not compacted during shaping, causing poor densification and strength. …
1. Introduction. Concrete is a sustainable and versatile construction material which can produce structures that last for thousands of years. Due to the many areas of application, concrete is the second most consumed material on Earth, only after water, with a global production of around 4.1 billion tons of cement in 2021 (Statista, 2023), and an …

The cement industry is facing numerous challenges in the 21st century due to depleting natural fuel resources, shortage of raw materials, exponentially increasing cement demand and climate linked environmental concerns. Every tonne of ordinary Portland cement (OPC) produced releases an equivalent amount of carbon dioxide to …
Challenges to achieving zero emissions in the cement industry stem in large part from the raw materials, such as limestone and crushed rock, that are widely available, and the well-established manufacturing technology used for cement production, which has been difficult to innovate. 11 While cement is just one constituent in products like …
This review paper examines the use of wood ash as an ecological binder in two different applications: as a cement replacement and as an alkali-activated material.
Alternative binders. Although ordinary Portland cement currently dominates concrete production, there are alternative binders being developed that lower both process and energy-related CO 2 emissions.. The primary constituents of ordinary Portland cement are two calcium silicate minerals: alite, which is responsible for early strength gain, and …
Hydrated lime or Portland cement clinker can be used as a source of Ca 2+ ions. Here, as an alternative, micronized WM was used as a source of Ca 2+ ions in solution, in combination with GGBFS (XRF composition reported in Table 3). A one-part alkali-activated binder was formulated by blending 47.5% GGBFS, 47.5% WM and 5% …
Fondustep mortar is a bauxite specialty binder that resists H 2 S corrosion better than a mortar composed of standard specialty binder and even PMSR. It can be applied manually or by mechanical sprayer, sets quickly to be ready for use, and can be used in cold conditions (max 0°C). It carries a COV A+ classification.
Geopolymers were used in many ancient constructions and the building units of geopolymer consist primarily TO 4 tetrahedrons (where T is Si or Al) [10], [11].The concrete made from geopolymer cements has good engineering properties [12], [13], [14] and appears to be a good alternative to conventional concrete. Geopolymeric concrete …
Surface Test Type A for Concrete and Hot-Mix Asphalt Surfaces; ... a PG 64-22 base binder can be used in most locations. It is the most commonly used binder by the department and is frequently used for subsurface mixes and low volume pavements. A few areas of the state with desert conditions may require PG 70 rather than 64.
Some of the binders such as CSA cement and MgO cement can replace conventional OPC clinker. 2. The conventional raw materials and fuels, used to produce OPC clinkers, can be replaced fully or partly to develop newer cements. 3. CSAB cement can save energy up to 25% with reduction of limestone quantity and CO 2 by 60 and …
The choice of solvent-based binders in metal injection molding can significantly impact the final properties and characteristics of molded metal parts. By comparing different binder types, the effects of binder choice can be better understood. Can Wax-Based Binders Be Used for Complex Geometries in Metal Injection Molding?
At this point the slaked lime is combined with sand in a 1:2-3 v/v ratio to produce a lime mortar that can then be used in the laying of masonry units or as a plaster or stucco. ... Natural cement is a hydraulic binder with rapid setting due to the production of calcium aluminate hydrates. 9 As a binder, natural cement has a high compressive ...
A new study finds supply-side efforts alone are unlikely to lead to net-zero emissions across the cement and concrete cycle by 2050, advocating for more efficient use of cement and concrete in the ...
CSA cements have been used in China as a binder for concrete in bridges, leakage and seepage prevention projects, concrete pipes, precast concrete (e.g. beams and columns), prestressed concrete elements, waterproof layers, glass fiber reinforced cement products, low temperature construction and shotcrete [23,24,26,27,30].
Portland cement binders for mortars and renders have a similar appearance in thin section to the cement matrix of hardened concrete. Figure 309 shows a typical uncarbonated Portland cement:sand mortar with an isotropic matrix of calcium silicate hydrates including dispersed portlandite (calcium hydroxide) crystallites (first-order red and second-order …
Since concrete is the most popular material in the world and cement is the primary binder used in concrete, these two sources of CO 2 are the main reason that cement contributes around 8 percent of global emissions. CSHub's Executive Director Jeremy Gregory, however, sees concrete's scale as an opportunity to mitigate climate …
These alternative binders can be used as substitutes for traditional cement in concrete production, further reducing CO 2 emissions associated with the manufacturing process. CCU technologies in concrete production not only help to mitigate CO 2 …
Substitution of cement constituents (e.g., clinker), cement, binder, and concrete/mortar are possible.
A paint binder is the substance that holds the paint together. Just like one would use cement as a binding agent to create concrete to build houses. Or how a chef would use eggs — which have highly elastic proteins that create a web that holds other ingredients together — to coat their meat before dipping it into flour for frying.
Alternative binders. Although ordinary Portland cement currently dominates concrete production, there are alternative binders being developed that lower both process and energy-related CO 2 emissions.
Stripped of precious metals, the residue contains calcium, silicon, aluminum, and iron and functions as a CO 2-free cement …
The cement has potential to be used in more sustainable buildings and cities in future, such as to light footpaths, swimming pools, interior rooms, and roadways, etc. However, the process to give the cement its light-emitting capability changes the structure of the cement, meaning it can be used only for surface coatings.
The use of Portland cement in the binder has a significant role in providing strength to the concrete in comparison to only lime-based binders [4]. However, because of the large amount of CO 2 that is generated in the production of Portland cement and even hydrated lime, other admixtures such as meta -kaolin to reduce the carbon …

Mexico's largest cement producer, Cemex (see elsewhere in this issue) was founded in 1906, and its second largest, Cementos Apasco, was organized in 1928. Ultimately Cemex cornered the export market, while Apasco (bought by the Swiss conglomerate Holcim in 1964) dominates the internal market for cement products. ...
