To prevent segregation and bleeding in concrete a some decade ago started practicing of fiber addition in concrete this gave a good result M30 mix is considered for work with 1% of fiber addition i.e 0.5% of Polypropylene + 0.5% of Hooked end Steel Fiber, with 0.45 w/c ratio and 1.5% of super plasticizer for workability of concrete. Conducted various tests like Slump cone test, compressive test, spilt tensile test, flexural test, and shear test for concrete. Then FRP product E-Glass fabric or GFRP used for lamination purpose of 900 gsm to specimens then laminated specimens are also tested above mentioned experiment expect slump test. Results are compared after 28 days of curing with normal concrete to hybrid concrete and with GFRP to without GFRP lamination. Result has shown increase in strength with normal to hybrid concrete and also increase in with GFRP lamination when compared to without GFRP lamination.

Analysis of some geotechnical problems using finite-element methods requires the implementation of a nonlinear model for soil materials, to better represent their actual behaviour. Constitutive modelling of soil mass behaviour and material interfaces is an essential component of the solution of boundary and initial value problems. The hyperbolic model is one of the most frequently used non-linear models for predicting the behaviour of soils in boundary value problems. The parameters of this model for specific soils need to be determined experimentally. This paper presents the results of extensive laboratory testing carried out on three soils from the Eastern Province of Saudi Arabia: sand, marl and sabkha. The tests used to obtain these results were the triaxial compression test, the hydrostatic (isotropic compression) test, and the direct shear test. Additionally, other tests were used to obtain various physical properties needed for the complete characterisation of these soils. Pa...

Bamboo in an extraordinary nature material. Bamboo can grow fast, the price is cheap, and available everywhere. The weight is light but it is harder and stronger than regular wood and fiberglass. The main purpose of this research is to know the impact of open air and emersion of seawater to the part of fiber of petung bamboo towards interface bond, epoxy matrix, of the lamination of the bamboo. This research has conducted a compression test, tensile test, and shear test towards the interface bond in the direction of x,y, and z axis using the standard of ASTM D143. The changes of open air impact happened from week 0 to 9 reach the number of 40% and the emersion of seawater was 70%. The average results obtained 9 weeks for the influence of open air and sea water is a tensile test of 33.68 kg / cm2, 21.72 kg / cm2. Shear test of 24.37 kg / cm2.13.87 kg / cm2. Compressive test 333.53 kg / cm2, 316.80 kg / cm2. The average compressive strength of laminated bamboo after undergoing treatment for 9 weeks can be classified into Class II and Class III in BKI Ship Kayu regulations. The test results show that the tensile strength and compressive strength better brick arrangement, while for shear strength better aligned. The best tensile strength test direction on the Y axis, the best shear strength test direction on the Z axis, and the best compressive strength test direction on the X axis. The higher the Interface resin value at each cm2, the greater the strength of the interface bond due to the need for resin in mm / cm2 the higher, conversely the lower the value of Interface resin in each cm2, the lower the bond strength of the interface due to the lower resin requirements in mm / cm2.
