Influence of Cockle Shell Ash and Lime on Geotechnical Properties of Expansive Clay Soil Stabilized at Optimum Silica Fume Content Muhammad Syamsul Imran Zaini1,a, Muzamir Hasan1,b*, Anang Rustanto Suwito1,b and Masayuki Hyodo2,d 1Faculty of Civil Engineering Technology, Universiti Malaysia Pahang Al-Sultan Abdullah, Lebuh Persiaran Tun Khalil Yaakob, 26300 Kuantan, Pahang, Malaysia 2Graduate School of Science and Technology for Innovation, Yamaguchi University, Ube, Japan aSyamsulimran94@gmail.com, bMuzamir@umpsa.edu.my, canangsg8@gmail.com, dhyodo@yamaguchi-u.ac.jp Keywords: Consolidated Isotropic Undrained Triaxial Test, Field Emission Scanning Electron Microscopy, Kaolinite Clay Soil, Soil Improvement, Unconfined Compressive Test, X-ray Diffraction.
The engineering properties of the kaolinite soil are shown in Table 1.
The study concluded that CKSA and lime significantly enhanced the engineering properties and strength of SFSS, due to their high calcium oxide, silicon dioxide, and aluminium oxide content, resulting in substantial improvements in the soil's engineering properties and shear strength.

Experimental Study on Cracking Property of Self-Compacting Concrete Nanguo Jin1,a , Xianyu Jin1,b and Xianglin Gu2,c 1 Department of Civil Engineering, Zhejiang University，Hangzhou 310027,China 2 Department of Building Engineering,Tongji University, Shanghai 200092 ,China a jinng@zju.edu.cn, b xianyu@zju.edu.cn, c gxl@mail.tongji.edu.cn Keywords: self-compacting concrete, crack, characteristic age, ultimate flexural tensile strain Abstract: Taking free shrinkage as the key parameter in evaluating cracking of concrete, the cracking properties of self-compacting concrete with strength grade of C35 and C50 were investigated based on ring and slab restraint tests.
Due to the extraordinary good workability of self-compacting concrete, common visible defects of concrete, such as holes, beehives and rough surface, can be avoided in the construction, and it is especially good to use self-compacting concrete as the main material for parts of an engineering project where it is hard to vibrate when cast the concrete in construction.
So, all of the factors listed before, which will affect the cracking property of concrete, can be considered in the study to figure out the valuable results for the engineering application.
Referring to the actual engineering condition, the curing temperature for specimens was controlled between20 2 oC , and the humidity was 40±5%.

Scheme1: Reinforced Concrete Frame Column + RC Transfer Girders + Shear Wall Advantages: It is a normal design scheme, and is widely used in practical engineering.
It is easy to engineering calculations, design and construction, and the cost is more efficient.
According to the engineering characteristics, main features was selected in order to minimize the effect of the shear wall eccentric above the transfer storey as following: Transfer storey: The main rib of the axial layout of the frame-supporting column at the bottom: 600mm×3300mm, the main ribs at 12.2m pillar space: 800mm×3300mm; secondary ribs: 400mm×3300mm; the top plate thickness: 300mm, the base plate thickness: 250mm.
After some discussion with equipment engineer, the round hole is proved to be beneficial to the reduction of the stress concentration and enhancement processing.

Introduction With the advantages of high water head bearing, reliable impermeable performance and adaptability of construction conditions, concrete cut-off wall was widely used in water resources and hydropower engineering projects in our country[1].
With the development of finite element analysis in geotechnical engineering, a series studies on cut-off wall stress deformation were carried out using numerical calculation method by domestic scholars [2-4], and made a lot of useful results.

Verified from engineering practices and experimental researches, like structural parameters, process of carbonation and chloride penetration are subject to uncertainties.
Considering the development of concrete technique and requirement of engineering quality, the upper limit of probability of failure is fixed on 10% in this paper, and b=1.2816 accordingly.
The model and the corresponding service life prediction method need to be improved and verified by more data from practical engineering and compliance tests.
