This research was carried out on Punicagranitum L. grown near Abbaseen stone crushing plant at Kuchlak District Quetta of Balochistan, Pakistan. The investigation was aimed to understand the adverse effects of stone crushing dust pollution on morphological, physiological, growth, fruit quality and productivity of Punica granatum L.. The plants leaves and fruits were collected from three polluted sites with the distance of 200, 400 and 600 meters away from the stone crushing units respectively. Whereas a locality of 5000 meters away from stone crushing location comparatively clean air considered as a control sampling. Results showed that the dust load on the leaf surface was reported (1.16, 0.84, 0.62 and 0.13µg/cm2) at location 200, 400, 600 and 5000 m sites respectively. The site nearest (200 m) to the stone crushing units, contained highest dust amount showed significant destructive effects on the leaf physio-morphological characteristics, fruit yield and quality characteristics of Punica granatum L. The consequences of this study also revealed that a fine aerosol of stone dust is emitted from the crushing units has significantly effects on plant height (110.6-144 cm), Stem size (18.42-24.06cm) and tree canopy (108.6-142.0 cm2). Petiole length, leaf length, breadth and Leaf area near to the stone crushing units was found; 0.3-0.6 cm, 5.3-6.6 cm, 1.9-2.6cm and 6.2-7.2cm2. Leaf relative water content (41.83-75.23%) and Fruit Moisture Content (58.21-77.43%) was also noted significantly less at polluted site. More number of closed stomata/ cm2, decrease in photosynthetic rate and transpiration rate and stomatal conductance with an enhanced level of sub stomatal CO2 concentration was also reported near the crushing unit with respect to the control site. Results also showed less chlorophyll contents at polluted site. Number of fruits/tree and Fruit Size was also noted significantly low as compared to control site (5000 m). From the result it was concluded that the distance is directly proportional to the growth, yield, physiological and morphological characteristics of this plant.

Comaron is an easy solution for construction materials in India. Stone dust is a waste material attained from crusher plants. It has possibility to be used as fractional replacement of natural river sand in concrete. Consumption of stone dust in concrete not only increases the period of concrete but also look after the natural river sand for coming generations.

The main objective of this research is to investigate the use of fly ash and other is Stone dust as partial replacement of cement and concrete production. In this research we analyze the strength of concrete made with using these waste materials one is Fly ash and other is Stone dust. The Fly as his used as 20 replace by weight of cement and Stone Dust as the partial replacement of Fine Aggregate from 0 , 10 , 20 , 30 and 40 . The grade of the concrete here is M-30 grade.

Concrete is the most widely used construction material today. Increase in construction activities have led to an increase in demand for the various raw materials in concrete, especially river sand which is the conventionally used fine aggregate. Due to increase in mining process, the availability of this river sand is becoming scarce. This led to researches on alternate materials as ingredients of concrete that are in no way inferior to the conventional materials. Manufactured sand was one of the alternate materials proposed. Though manufactured sand has many advantages, one of the major areas of concern is the fine material of size 150 micron and down removed during the manufacturing process and accumulated as a waste material. The paper presents the laboratory investigations and a comparative study on the mechanical properties and behaviour of high strength concrete an mortar using fine stone dust, the residue produced during the production of manufactured sand.
