Concrete dust odor complaints: sources, causes, mitigation Common Sources of Concrete Dust in Air Building Dust. Concrete drygrinding for refinshing or resurfacing. Concrete saw or cutting operations in walls, floors, or ceilings after construction such as for the insertion of control joints or to create openings.
THE EFFECT OF QUARRY DUST WITH CEMENT BYPRODUCTS ON PROPERTIES OF CONCRETE. The numerous demanding application of concrete is not readily met with Ordinary Portland Cement (OPC) alone. To meet up the demand and as well as ensured the green concrete durability, it has becomes necessary to incorporate mineral additions with the best combination ...
Cement Plant Bag Filter. Bag filter for dust removal effect is good, have been widely used, of course, in addition to using bag filter effect is good, still have a lot of advantages, so today we are going to focus on the advantages of bag filter, introduced below is bag filter manufacturer.
IJRRAS 7 (1) April 2011 Rahman al. Literature Review on Cement Kiln Dust Usage in Soil 79 CKD sharply reduced the swell potential of the clay which was expansive in nature. The swelling of the raw clay, as determined by the ASTM D 4546 procedure, dropped from over 9% to 0% when treated with 25% CKD.
to High density polyethylene (HDPE), also the effect of polyethylene glycol (PEG) as compatibilizer on mechanical properties of the polymer composites. HDPE/CKD composites with various CKD content (0,2,4,6, and 8wt%) samples were prepared by melt extrusion followed by injection molding.
Summary: The effect of cement dust on exposed workers was conducted in Asaba Delta state Nigeria, to delineate the occupational hazards posed by cement dust on haematological parameters. The assessment of haematological parameters was performed in forty workers occupationally exposed to cement dust and forty matched unexposed control.
Dust from demolition processes can often have a profound effect on neighbouring areas. If dust is likely to spread into areas beyond the site, as it may do in unfavourable wind conditions, steps should be taken to assess the risk and to devise appropriate measures, (Guidance is given in Table, page 22).

ABSTRACT: To evaluate the impact of the cement's dust emitted by the eastern Moroccan cement factory (Oujda Holcim) and deposited on the soil of the Ain Lahjar commune, 58 samples of soil were collected around the factory on a radius of 3 km approximately. The physicochemical analyses of the upper 3 cm of the soil surface samples correspond
Jun 18, 2014· Fineness of cement has a great effect on the rate of hydration and hence the rate of gain of strength. Fineness of cement increases the rate of evolution of heat. Finer cement offers a great surface area for hydration and hence faster the development of strength.
investigation of effect of silica fume and quarry dust as partial replacements of cement and sand respectively on concrete. This effect has been studied on compressive strength, workability and durability of M25 concrete. Replacement levels of 8, 10 and 12% for silica fume and 20, 30 and 40% for quarry dust .
Background. There are only a few followup studies of respiratory function among cement workers. The main aims of this study were to measure total dust exposure, to examine chronic respiratory symptoms and changes in lung function among cement factory workers and .
