Performance Enhancer for Portland Limestone Cement (PLC)

The motives to replace clinker with supplementary cementitious materials (SCM) are well known. However, granulated blast furnace slag, natural pozzolanes, qualified fly ash and further SCM have a limited availability; the total potential replacement of the global clinker production is less than 30%. Limestone is increasingly being used as a component in Portland-Limestone cements: Sika offers an additive to enhance grinding and performance.

Addressing the Unwanted Impacts of Grinding Aids

Grinding aids and strength enhancers are well known for their ability to increase cement mill productivity, and the mechanical strength of mortar and concrete. However, little information is available on the potential drawbacks of their usage. To close the gap, Sika Services addresses the possible impacts on health and safety and the environment, and on cement properties in production and use.

The Science Behind Wood Floor Adhesives

The task of wood floor adhesives is to firmly bond the organic wood floor elements to the generally inorganic screed. The adhesive must hold the wood in place, connect it to the underlying screed and transfer stress originating from the natural expansion and contraction of the wood to the generally rigid screed. The undesired but natural movement of the wood can become visible in cupping, joint formation, or in extreme situations failure of the adhesive or screed.

Progress with Grinding Aids for Vertical Roller Mills

The effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles.

Products for Fast Excavation with Microtunneling

Tunnel boring machines (TBMs) are commonly found with diameters from five to 17 meters. There are also microtunnel boring machines which are smaller, with an excavation diameter up to four meters. Today, they are extensively used to construct many kilometers of underground infrastructure worldwide. Microtunneling is a fast alternative to conventional pipe installation systems, since it is a fully automated method of boring and pipe installation without the need for disturbing the surface.

Considerations for Facade Joint Design

The facade is the face of buildings. In contemporary architecture, the facade is of special interest expressed by large dimensions, unconventional shapes and high material diversity. Especially with these unique shapes and connections, joint design is demanding and prone to mistakes. For integral joint specification, following some rough guidelines will result in a long-lasting and tight building envelope.

Potential Screed Issues and Solutions

If the screed is even, strong and dry enough, then only mechanical surface preparation such as grinding and cleaning is required, before wood floor bonding is possible. However there are many situations where the existing or even new screeds are not suitable, and additional treatment is necessary before wood flooring can be installed. Sika has developed complete balanced system solutions for all of the different possibilities that may be found in these situations.

Watertight Concrete System

Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts and cracks.

What is Radon & How to Protect Against it in Buildings

Ensuring the safety and integrity of structures in contact with the ground includes not only watertightness but also protection against radon – a hidden yet significant health hazard. Radon protection systems are essential in buildings to prevent the accumulation of radon, a harmful, invisible, and odorless radioactive gas naturally emitted from the ground.

Injection Basics: Applications for Ground Consolidation, Stabilization & Waterproofing

Injection techniques are essential for strengthening and protecting structures and underground construction through ground consolidation, stabilization, and waterproofing. This article explores how injection works, its key applications, materials, and the benefits of using injection as a reliable solution across construction, tunneling and mining projects.

Go Pouch - Less Waste, More Savings

There is a clear reason to switch to pouch packaging due to waste disposal and cost saving reasons in almost all industries. Compared to rigid bottles which remain in a 3D shape after the product has been used, pouches can be easily flattened into a 2D shape. Lighter, space-friendly, flexible shape, less material to produce - there is a list of advantages to convince producers like Sika to go for it.

Tank Level Management

Efficient management of concrete admixture stock levels is incredibly important, as late replenishment can result in costly delays and unhappy customers. At the same time, it’s difficult to find the time and personnel to check admixture stock regularly, so orders can be placed without accurate stock information.

How to Design an Ideal Floor for Warehouse and Logistics Facilities

In warehouses and logistics buildings the concrete slab and flooring are critical to the effective functioning of the operations. However, it is often the perception that the concrete floor is one of the most straight forward elements of the project, and many times the overall attention paid to design and construction detail is less than proportional to its ultimate importance in the efficient operation of the facility. The expectation is that these large area floors must be constructed with lowest possible cost and provide problem free service year after year.
