Distinguishing Natural Quartz and Quartzite – No More Confusion

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.

Eco-Friendly Paving: Let the Water Flow Through

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.

Combining Integrated Circuits and Sensors in Bricks: A Smart Architecture Solution

In the era of digital technology and the explosive growth of the Internet of Things (IoT), architecture is no longer merely the art of construction—it has evolved into an intelligent ecosystem, where buildings can sense, analyze, and respond to their environment. One of the most advanced solutions driving breakthroughs in modern construction is the sensor-embedded brick with integrated circuits. This is no longer a passive traditional building material, but rather a “sensing brick,” equipped with internal sensors and processing microchips capable of measuring temperature, humidity, vibration, and impact forces, and wirelessly transmitting data in real-time. The application of this technology in construction not only enhances the ability to monitor structural safety but also unlocks the potential for smart, sustainable, and energy-efficient buildings. This topic aims to clarify the role of integrating sensors and microchips into building bricks, the manufacturing process, and notable practical applications.
