The Veluwemeer Aqueduct, located near Harderwijk in the Netherlands, continues to captivate visitors worldwide. This innovative structure, built in 2002, allows the N302 road to pass under the Veluwemeer lake while boats sail seamlessly above. Spanning 25 meters and with a water depth of 3 meters, it’s a symbol of Dutch expertise in integrating transportation and water management.
Blending function and beauty, the aqueduct is also a popular tourist attraction, offering pedestrian walkways for stunning views of this engineering wonder. It exemplifies how infrastructure can harmonize with nature and recreation.

In mass concrete construction, the heat of hydration has always been a “hidden variable” that troubles many engineers and contractors. When cement reacts with water, an enormous amount of heat is generated and trapped inside the massive concrete body. Without proper control, excessive temperatures and the temperature gradient between the core and the surface can cause dangerous thermal cracks, threatening both the durability and safety of the structure. This challenge is not just theoretical—it has been marked in history with a classic lesson: the Hoover Dam (USA), one of the greatest concrete megastructures of the 20th century. Containing millions of cubic meters of concrete, the dam would have taken hundreds of years to cool naturally. Engineers had to devise unprecedented solutions: segmenting the mass, actively cooling it through a network of circulating cold-water pipes, and applying a combination of innovative measures to bring the concrete temperature down to safe levels.

Have you ever wondered why modern buildings with large glass facades remain cool in the summer yet warm in the winter? The secret lies in Low-E (Low-Emissivity) glass technology. In contemporary construction, glass is no longer just a material for natural lighting but also an essential solution for enhancing a building’s energy efficiency. Low-E glass is coated with an ultra-thin, nearly invisible layer of metal oxide that works “intelligently” to control heat radiation. It allows natural daylight to enter while blocking most infrared and ultraviolet rays that cause heat buildup and potential health risks. Thanks to these properties, this advanced glass not only creates a more comfortable living environment but also significantly reduces heating and cooling costs, while contributing to sustainability and environmental friendliness in modern architecture.

In the world of natural stone, quartz and quartzite are two names that are often confused—not only because their names sound similar, but also because their appearance shares many similarities. However, they are entirely different materials in terms of origin, structure, and performance characteristics. Quartz is typically an engineered stone, created by combining crushed quartz crystals with resin and additives, while quartzite is a natural stone formed through the metamorphism of quartz-rich sandstone. This difference not only impacts the value of the material but also determines its durability, heat resistance, and suitability for various applications. Understanding how to distinguish between quartz and quartzite will help you choose the right stone for your needs, avoid mistakes, and make the most of your investment.

In areas with high slip risk—such as bathrooms, swimming pools, public lobbies, or sloped surfaces—selecting tiles with adequate slip resistance is essential. To accurately assess this property, there are currently four widely used testing methods, each aligned with different international standards and suited to specific applications. This article will help you understand each method, how to interpret the results, and how to apply them effectively in real-world scenarios.

Hinoki wood (Japanese cypress – Chamaecyparis obtusa) is a precious type of wood native to Japan, known for its light color, fine grain, and pleasant natural aroma. Thanks to its antibacterial, moisture-resistant, and heat-resistant properties, Hinoki has long been used in traditional architecture, such as temples, onsen bathtubs, and especially saunas. With its calming fragrance and exceptional durability, Hinoki is increasingly favored in modern bathroom design, offering a luxurious and serene experience for users.

In the context of rapid urbanization, localized flooding and water pollution are becoming increasingly severe, particularly due to stormwater runoff on impermeable surfaces such as concrete and asphalt. Permeable pavers have emerged as an advanced, environmentally friendly construction material designed to reduce stormwater runoff and filter pollutants at the source. Not only do these pavers allow for rapid water drainage, but they also act as a primary filter that traps dust, heavy metals, and vehicle-related contaminants, thus improving urban environmental quality. This material is a part of the new wave of sustainable construction trends, widely adopted in developed countries but still relatively new in Vietnam.
