摘要： PROBLEM TO BE SOLVED: To provide a cement-based hardened body whose surface is free from the formation of dissimilar parts in color and has beautiful appearance, and which prevents the generation of rust in a metal fiber even when the metal fiber is used, and maintains the beautiful appearance of its surface for a long period of time.
SOLUTION: The cement-based hardened body is a hardened body of a formulation containing at least cement, a pozzolan-based fine powder, a fiber, a water reducing agent, and water, and the thickness of a part covering the fiber is ≥0.5 mm. Incorporation of an inorganic powder having an average particle diameter of 3-20 μm into the formulation is preferable because the cement-based hardened body is made denser, and strength developability and wear resistance can be improved. Further, incorporation of a fine aggregate into the formulation is preferable from viewpoints of the improvement of flowability of the formulation and strength developability and wear resistance of the hardened body, the reduction of self-shrinkage or dry shrinkage, lowering of the calorific value at hydration, or the like.

摘要： PROBLEM TO BE SOLVED: To solve such problems that, conventionally, since high-purity silica, alumina, or the like, each used as a fusion preventive material, is expensive and also the used fusion preventive material is disposed as waste almost without being recycles, the production cost of artificial lightweight aggregate is raised by the use of such a fusion preventive material, and also, cost for the waste disposal is required. SOLUTION: This artificial lightweight aggregate production process using a rotary kiln 2 involves using limestone L as a fusion preventive material for preventing fusion of pieces of aggregate to each other or to the shell inner surface of the rotary kiln 2, which fusion is caused by fine powder of raw material aggregate P, wherein the amount to be added of the limestone L is preferably 0.5-10 wt.%, the limestone L is blown into the rotary kiln 2, and by recovering quicklime Q1 and quicklime Q2, each formed from the blown limestone L, from a gas exhaust system of the kiln 2 and the surface of aggregate A discharged from the kiln 2, respectively, the need for performing waste disposal of the used fusion preventive material can be eliminated.

摘要： PROBLEM TO BE SOLVED: To improve the productivity in manufacturing artificial lightweight aggregate by preventing cohesion of aggregate particles themselves, that of aggregate particles to the shell surface of rotary kiln, and preventing interruption of firing by rough surface formed by adhesion of aggregate particles to the shell surface, which are caused by the presence of fine particles of raw aggregate. SOLUTION: The method uses a rotary kiln 2 to manufacture artificial lightweight aggregate, which contains drying, sintering, and bloating processes of raw aggregate and additionally a process to remove fine particles of raw aggregate from the kiln 2 before they reach the bloating temperature. Removing of fine particles is preferably implemented in a range where aggregate shows a dropping strength of >=85% of that of sintered aggregate or a crushing strength of >=10 kgf. Fine particles are removable to outside from the kiln by using a heat-resistant screen at the middle of kiln 2 or at connecting positions of a plurality of rotary kilns 11, 12, 13.
