Waste marble dust has been used as an additive material in blended cement for cement manufacturing [13]. Most of the studies have focused on the replacement of marble dust with cement in the cement mortar [12]. SEM test was conducted on the mortar sample. Optimum percentage of marble dust in concrete was not defined.
Locally available ordinary Portland cement (OPC grade) with a Blaine fineness of 379 m 2 /kg was used. Marble powder (MP) was produced in Henan Province, China. The specific gravities of cement and MP were g/cm 3 and g/cm 3. The mineralogical phase composition of cement and MP was examined by XRD and the result is shown in Fig. 1.

A powder obtained as a byproduct of marble sawing and shaping was characterized from a chemical and physical point of view in order to use it as mineral addition for mortars and concretes
The use of waste marble powder (dust) was proposed in partial replacement of cement, for the production of Mortar and Concrete Mix. In particular, tests were conducted on the mortars and concrete mix cured for different times in order to determine their workability, flexural as
Oct 16, 2020#0183;#32;This paper aims at giving new insights into the impacts of the particle sizes of diatomite waste on the hydration properties of Portland cement from the perspective of quantitative analysis using Rietveld refinements method. XRD identification coupled with Rietveld quantitative phase analysis, as well as isothermal calorimetry and SEM observation, was performed.
Marble dust can be mixed with various types of cement to form precast marble molded concrete. There are two types of cement that can be mixed with marble that will form a product that is hard and resilient: type S and Portland cement. The mixing methods, however, are the same.
Marble Dust Powder (MDP) is a developing composite material that will allow the concr#232;te industry to optimise materiel use, generate economic benefits and build structures that will strong
Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and nonspecialty was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker
Analysis ment, Ordinary Portland cement CaO SiO2 Al2O3 Fe2O3 MgO K2O SO3 Na2O3 Marble powder A marble powder was used, which was obtained as a byproduct of marble sawing and shaping. Its specific gravity was kg/m3 and the value of Blaine fineness was m2/g.

Production of the raw feed to obtain the ideal proportioning of materials. Crushing reduces the materials to tiny fragments of 25 to 40 mm, which are then ground into a fine grey powder (lt;200 microns), and the powder obtained is stored in silos. Calcination. The feed is heated to produce clinker, the raw material for cement.
This paper is devoted to the study of the hardening process and the mechanical properties of composite cements. There were three mineral additions and two polymer ones, namely fly ash, limestone meal and marble powder, polymer dispersion and redispersible polymer powder used. The principal possibility of combining mineral fillers in the design of composite cements is shown.
marble powder, which presents a strong argument for its use as a concrete addition. 2. Materials Used . Cement . The Portland cement has a Blaine Specific Surface (BSS) of 3830 cm2/g. It is a CEM II / A clinker with addition of 10% limestone. The cement is marketed by Egyptian Orascom Group (Algerian Cement Company).
#0183;#32;In order to promote the utilization of waste marble powder (WMP) in cementbased materials, an attempt to improve the mechanical properties of cementWMP system by incorporating nano silica (NS) was made in this study. 16 mortar mixes incorporating NS (0%, 1%, 2% and 3%) and WMP (0%, 10%, 20% and 30%) as partial replacement of Portland cement were designed.
