4. COMPOSITION For producing high density concrete it uses heavy natural aggregates such as barites or magnetite or manufactured aggregates such as iron or lead shot The density achieved will depend on type of aggregate used typically using barites the density will be in the range of 3500kg/m³ (45% greater), while with magnetite the density will be …
WhatsApp: +86 18221755073Ferrocement is a type of thin reinforced concrete made of cement mortar reinforced with closely spaced wire mesh. It has a higher ratio of steel to cement than conventional concrete. Ferrocement was invented in France in the 1840s and provides high tensile strength, durability, and versatility due to its composition and thin walls.
WhatsApp: +86 18221755073It defines HSC as concrete with a 28-day compressive strength of over 40 MPa. HSC uses a low water-cement ratio, smaller aggregate sizes, and admixtures like silica fume and superplasticizers. Compared to normal-strength concrete, HSC has higher resistance to pressure, modulus of elasticity, and strength gained at an earlier age.
