Cement concrete is the most extensively used material for construction of different types of structures components such as buildings, bridges and shell roofs and also for precast products such as pipes, poles, sleepers, ect. Concrete is defined as any solid mass made with the use of a cementing medium; the ingredients generally comprise sand, gravel, cement and water. Concrete has been in use as a building material for more than two hundred years. Its success and popularity may be largely attributed to (i) durability under hostile environments (including resistance to water), (ii) ease with which it can be cast into a variety of shapes and sizes, and (iii) its relative economy and easy availability. Super plasticizers in concrete confer some beneficial effects such as acceleration, retardation, air entrainment, water reduction, plasticity ect., M-sand is as fine aggregate partially. Cost vice M-sand is better than normal river sand. In this present experimental investigation M25 concrete is used as control mix with M-sand and super plasticizer and glass fiber in various percentages. Strength of modified concrete is compared with normal concrete. The results show that the significant improvement in the strength and workability of modified concrete.
