Ver artículo1. Introduction. The construction industry and all those related to cement derivatives consume a large amount of natural resources. The extraction of natural aggregates used for the manufacture of mortars and concrete is subject to growing problems due to the depletion of the quarries, the negative impact it produces on the environment and regulatory requirements.
Ver artículoThe concrete industry uses these materials, which would normally have to be disposed in land-fill sites, to the advantage of concrete. The materials participate in the hydration reaction and significantly improve the strength, permeability and durability of concrete. Other Ingredients. Aggregates for concrete are chosen carefully.

Ver artículoTo achieve the required concrete density to absorb the radiation a combination of high-density aggregates steel shot (fine aggregate) and hematite iron-ore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately R370.00 to R7 600.00 per cubic metre of concrete in 1996.

Ver artículoHigh Quality Portable Automatic Soil Non-Nuclear Electrical Density Gauge The Electrical Density Gauge (EDG) is a nuclear-free alternative for determining the moisture and density of compacted soils used in road beds and foundations.
Ver artículoRecycled aggregates were widely used in the concrete industry as a replacement of natural aggregates in the last two decades. In this study, the resistance of concrete mixtures having various levels of recycled aggregate as a replacement of natural coarse aggregate to the attack of magnesium and sodium sulfates was investigated. Five mixtures made with 0%, 25%, …
Ver artículoSieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4)
Ver artículoDensity is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.
Ver artículoWhen using only MagnaDense as a high density aggregate, concrete with densities up to 4.0 t/m 3 is achievable. Mixing MagnaDense into concrete with other aggregates allows you to produce even heavyweight concrete with densities up to 5.0 t/m 3. With the correct mix design, high-density concrete can still achieve good workability.
Ver artículoAnswer: Thank you Asif Asby for A2A We generally consider following density for estimation of quantity of these materials. Sand = 1920 kg/ m^3 Aggregate = 1520 kg/m^3 Cement = 1440kg/m^3 Density of sand in different conditions:- Sand, wet : 1922 Sand, wet, packed: 2082 Sand, dry :1602 Sand...
