Dry Shake Hardeners for Concrete Floors

Dry shake aggregate floor hardeners are commonly applied to the surface of freshly placed concrete to improve wear resistance and occasionally to color a concrete surface. They decrease typical plain concrete negative properties like dusting and liquid absorption by improving the abrasion resistance and reducing surface permeability.

Cool Roofs in Hot Climate Countries: a Study

Cool roofs are one of the most effective and easiest solutions to increase the thermal comfort of buildings and reduce cooling costs in hot climate countries with high solar radiation and outdoor temperatures. Brunel University London, in cooperation with the European Cool Roofs Council, Sika Services AG and the University of Technology in Kingston, evaluated a project in Jamaica to study how the application of a solar roof can affect the thermal comfort of residential buildings in hot climates.

Cool Roofs Reduce Urban Heat Island Effect

Many urban and suburban areas have higher temperatures than their rural surroundings. This temperature difference indicates that they are urban heat islands. The annual mean air temperature in a city of a million or more people can easily be 1 to 4°C warmer than in the rural surroundings. On a clear, calm night the difference can measure even 12°C or more. The main cause of urban heat island effect is the modification of the land surface in cities. Natural vegetation is replaced by the built environment. Most surfaces of new structures are characterized by low solar reflectance and high impermeability. Additionally, they are often built with high-density materials which absorb great amounts of thermal energy and release it as heat.

How to Select an Injection Material to Seal Leaks?

Leaks in concrete, masonry and natural stone structures can often be securely sealed and waterproofed by injection. However, to make leaking structures watertight for the long term, it’s essential to select the right injection material. On the basis of our extensive technical and practical experience, we have prepared a guide which will help you choose the optimal injection solution for your project requirements.

Microtunneling Products for Fast Excavation

Tunnel boring machines (TBMs) are commonly found with diameters from five to 17 meters. There are also microtunnel boring machines (MTBMs) 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.

Sprayed Concrete

Successful sprayed concrete requires the combination of many aspects of modern concrete technology especially concrete admixture chemistry, together with modern materials handling technology. The increasing demands for cost-effectiveness and the protection of health and the environment mean that sprayed concrete has been in continuous development. Thanks to more than one hundred years of experience, expert knowledge and a focus on performance and economy, Sika is able to provide the newest generation of sprayed concrete solutions.

3D Concrete Printing

Cementitious 3D construction printing (3DCP) or 3D concrete printing is a form of additive manufacturing used to fabricate buildings or construction components in completely new shapes not previously possible with traditional concrete formwork.

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.

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.

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.

Slip Resistant Flooring in Food Industry for Employee Safety

Employee safety is one of the most important requirements for any workplace. Slips and falls are among the most common injuries at work. They account for about 86% of total injuries, and 90% of these happen because the floor is wet. These injuries are particularly prevalent in the food industry, where they occur four times more often than the average in other industries. Injuries can create significant impacts to all involved. The most significant is the suffering and possible disabling of the person injured. The next is impact on the company — financial, loss of key staff, loss of productivity, and liability.
