Materials Used in Concrete Block Production: Cement and Binders

Among the "Materials Used in Concrete Block Production," the most critical component is "cement," which provides strength and cohesiveness to the mixture. Cement hardens the concrete by reacting with water (hydration). At "CONMACH MACHINE," we generally recommend that manufacturers use "CEM I" or "CEM II" cement to achieve high-quality, standard-compliant blocks. Keeping the cement fresh and protected from moisture directly affects the final strength of the blocks. Choosing the right cement is the first step to ensuring the longevity and durability of products produced with the "CONMACH concrete block machine."

Materials Used in Concrete Block Production: Aggregate (Sand and Gravel) Selection

Aggregate constitutes a large portion of the "Materials Used in Concrete Block Production." Aggregate consists of two main components: sand (fine aggregate) and gravel (coarse aggregate), and forms the backbone of concrete. It is vital that the aggregate used in production is clean and free of clay and organic matter. Furthermore, the aggregate's granulometric distribution (grain size) is critical for optimal compaction. CONMACH Machine users must produce blocks with the highest density using aggregates with the ideal grain distribution to ensure the machine's vibration and pressing system performs optimally.

Materials Used in Concrete Block Making: Water and Chemical Additives

Another essential element in the "Materials Used in Concrete Block Making" list is "water." The water that reacts with cement must be clean, colorless, and of drinkable quality; it must be free of acids, oils, or alkalis. The amount of water establishes a balance between the concrete's workability and final strength; too little water hinders hardening, while too much water reduces strength. Additionally, "chemical additives" are used in some projects to improve the production process or block properties. These additives (e.g., set accelerators or water reducers) can help optimize the performance of the concrete mix in mass production with the "CONMACH concrete block machine."

Materials Used in Concrete Block Making: Pigments and Colorants

"Materials Used in Concrete Block Making" can meet not only structural but also aesthetic needs. Pigments and colorants are added to the mixture to achieve the desired color and appearance, particularly in the production of paving stones and decorative bricks. These pigments are generally iron oxide-based. It consists of fine particles that do not affect the concrete's strength. When producing colored concrete, CONMACH Machine users must ensure that the correct amount of pigments and cement are mixed together. Using high-quality pigments ensures that the concrete blocks produced with the CONMACH block machine retain their color for a long time, increasing the product's market value.
